Question

Which of the following functions represents the following graph?

graph begins in the third quadrant and increases until it levels off at negative 2, negative 1. Then the graph begins to increase again and continues to increase.

f(x) = the square root of the sum of x and 2 – 1

f(x) = (x + 2)2 – 1

f(x) = negative 1 over x plus 2

f(x) = (x + 2)3 – 1
