• Linear Functions Worksheets

The rate of change for this example is constant, which means that it is the same for each input value. As the time input increases by 1 second, the corresponding distance output increases by 83 meters. The train began moving at this constant speed at a distance of meters from the station. Representing a Linear Function in Function Notation Another approach to representing linear functions is by using function notation.
• Linear Functions

One example of function notation is an equation written in the slope-intercept form of a line, where is the input value, is the rate of change, and is the initial value of the dependent variable. In the example of the train, we might use the notation where the total distance is a function of the time The rate, is 83 meters per second. The initial value of the dependent variable is the original distance from the station, meters. We can write a generalized equation to represent the motion of the train. Representing a Linear Function in Tabular Form A third method of representing a linear function is through the use of a table. The relationship between the distance from the station and the time is represented in Figure. From the table, we can see that the distance changes by 83 meters for every 1 second increase in time. Figure 2. Tabular representation of the function showing selected input and output values Can the input in the previous example be any real number?
• 0022 Linear Functions And Equations

The input represents time so while nonnegative rational and irrational numbers are possible, negative real numbers are not possible for this example. The input consists of non-negative real numbers. Representing a Linear Function in Graphical Form Another way to represent linear functions is visually, using a graph. We can use the function relationship from above, to draw a graph as represented in Figure. Notice the graph is a line. When we plot a linear function, the graph is always a line. The rate of change, which is constant, determines the slant, or slope of the line. The point at which the input value is zero is the vertical intercept, or y-intercept, of the line.
• Questions On Functions With Solutions

We can see from the graph that the y-intercept in the train example we just saw is and represents the distance of the train from the station when it began moving at a constant speed. Figure 3. The graph of. Graphs of linear functions are lines because the rate of change is constant. Notice that the graph of the train example is restricted, but this is not always the case. Consider the graph of the line Ask yourself what numbers can be input to the function. In other words, what is the domain of the function? The domain is comprised of all real numbers because any number may be doubled, and then have one added to the product. Linear Function A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line where is the initial or starting value of the function when input, , and is the constant rate of change, or slope of the function. The y-intercept is at Using a Linear Function to Find the Pressure on a Diver The pressure, in pounds per square inch PSI on the diver in Figure depends upon her depth below the water surface, in feet.
• Year 9: ACMNA215 – Linear Functions Test

This relationship may be modeled by the equation, Restate this function in words. Figure 4. The pressure as a function of depth equals four hundred thirty-four thousandths times depth plus fourteen and six hundred ninety-six thousandths. The rate of change, or slope, is 0. This tells us that the pressure on the diver increases 0. Determining Whether a Linear Function Is Increasing, Decreasing, or Constant The linear functions we used in the two previous examples increased over time, but not every linear function does. A linear function may be increasing, decreasing, or constant.
• Linear Functions Problems With Solutions

For an increasing function, as with the train example, the output values increase as the input values increase. The graph of an increasing function has a positive slope. A line with a positive slope slants upward from left to right as in Figure a. For a decreasing function, the slope is negative. The output values decrease as the input values increase. A line with a negative slope slants downward from left to right as in Figure b. If the function is constant, the output values are the same for all input values so the slope is zero. A line with a slope of zero is horizontal as in Figure c. Figure 5. Increasing and Decreasing Functions The slope determines if the function is an increasing linear function, a decreasing linear function, or a constant function. For each of the following scenarios, find the linear function that describes the relationship between the input value and the output value. Then, determine whether the graph of the function is increasing, decreasing, or constant.
