Question

What is the y-intercept of the function f(x) = 2 ^x?
A.27
B.2
C. 6
D. 1

Answer 1

D

Explanation:

the y- intercept is the value of y on the y- axis where the function crosses.

the function crosses the y - axis when x = 0

substitute x = 0 into f(x)

f(0) =
`2^(0)` = 1

y- intercept is 1
