Question

Which equation is represented by the graph below?

A y=In x-3
B y=In x-4
C y=e^3 -3
D y=e^3 -4

Answer 1

D

Explanation:

I assume that for C and D, you meant e^x.

Since the function is defined at 0, eliminate A and B (since ln 0 is undefined)

Between C and D, we know that when x=0, e^x = 1. Since the y intercept of the graph is -3, this means the equation is y = e^x - 4.
