Question

Find a function of the form f(x) = a*bˣ

A) f(x) = 40 * (1/2)ˣ
B) f(x) = 20 * (1/2)ˣ
C) f(x) = 20 * 2ˣ
D) f(x) = 5 * 2ˣ

Answer 1

The correct function of the given form is f(x) = 20 * (1/2)ˣ (Option C).

Step-by-step explanation:

The correct function of the given form is f(x) = 20 * (1/2)ˣ (Option C).

To determine the correct function, we can compare the given options with the form f(x) = a*bˣ. In this case, a is 20 and b is 1/2.

So, the correct function is f(x) = 20 * (1/2)ˣ.
