Question

Identify the y-intercept (initial value) of the function f(x) = 2(4)ˣ.

A) 0
B) 1
C) 2
D) 4

Answer 1

The y-intercept of the function f(x) = 2(4)^x is 2. Hence, C) is correct.

Step-by-step explanation:

The y-intercept (initial value) of the function f(x) = 2(4)x is 2.

The y-intercept represents the value of the function when x is equal to zero. In this case, when x is zero, the function becomes f(0) = 2(4)0 = 2.

Therefore, the y-intercept is 2.
