Explain why the initial value of a function of the form f(x)=a(bx) is equal to a. 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:

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.
