Vertical Stretches and Shrinks of Exponential Functions
Question 2 • CA-Mathematics I
Sample Response: When you substitute 0 for the exponent x, the expression simplifies to a times 1, which is just a. This is because any number to the 0 power equals 1. Since the initial value is the value of the function for an input of 0, the initial value for any function of this form will always be the value of a. What did you include in your response? Check all that apply.Any number to the power of 0 equals 1.Any number times 1 equals the number.Multiplying the value of a by 1 will equal the
Answer
A
Any number to the power of 0 equals 1.
B
Any number times 1 equals the number.
C
Multiplying the value of a by 1 will equal the initial value.
Explanation
The response states that any number raised to the power of 0 equals 1, so choice A is included. It also says that multiplying a by 1 gives a, which covers choice B, and explains that this result is the initial value, covering choice C.
