Question
Instructions: Graph the following function. Then, state whether the function represents exponential growth or decay.y=(45)xš¦=(45)š„This function is exponential
Solution
To graph the function y = 45^x, you would follow these steps:
-
Identify the base, which is 45. This is a constant that is raised to the power of x.
-
Create a table of values to plot on the graph. Choose a few values for x (both positive and negative) and calculate the corresponding y values. For example, if x = -1, y = 1/45. If x = 0, y = 1. If x = 1, y = 45. If x = 2, y = 2025, and so on.
-
Plot these points on a graph. The x-values will be along the horizontal axis and the y-values along the vertical axis.
-
Draw a smooth curve through the points. The curve should start from the y-axis (if extended to negative infinity for x) and rise to the right.
This function represents exponential growth because the base of the exponent (45) is greater than 1. This means as x increases, y will also increase at an increasing rate.

Letās do an example together that is an exponential decay model.ProblemThe cost of a new car is $32,000$32,000. It depreciates at a rate of 15%15% per year. This means that it loses 15%15% of its value each year.Draw a graph of the carās value against time in years.Find the formula that gives the value of the car in terms of time.Find the value of the car when it is four years old.Ā SolutionThis is an exponential decay function. Start by making a table of values. To fill in the values we start with when t=0š”=0. Then we multiply the value of the car by 85%85% for each passing year. (Since the car loses 15%15% of its value, it keeps 85%85% of its value. 100ā15=85100ā15=85.) Remember 85%=0.8585%=0.85.Time Value (Thousands)0032321127.227.22223.123.13319.719.74416.716.75514.214.2The general formula is y=a(b)xš¦=š(š)š„. In this case yš¦ is the value of the car, xš„ is the time in years, a=32,000š=32,000 is the starting amount in thousands, and b=0.85š=0.85 since we multiply the value in any year by this factor to get the value of the car in the following year. The formula for this problem is:y=š¦= (( )x)š„Finally, to find the value of the car when it is four years old, we use x=4š„=4 in the formula. Remember the value is in thousands.y=32000(0.85)4=š¦=32000(0.85)4= At 44 years old, we expect the car to be worth $$ CheckQuestion 2
