Question

Which equation is represented by the graph below?

On a coordinate plane, a curve approaches y = negative 4 in quadrant 3 and then increases exponentially in quadrant 1. It crosses the y-axis at (0, negative 3).

Answer 1

y = e^x - 4

Answer 2

y = e^x - 4

Explanation:

The missing options are

y = ln x - 3

y = ln x - 4

y = e^x - 3

y = e^x - 4

The function is defined in quadrant 3 and increases exponentially, then it is not a logarithm.

f(x) crosses the y-axis at (0, -3). Replacing x = 0 the last option, we get:

y = e^0 - 4 = 1 - 4 = -3
