Question

Use the following graph of quadratic function f(x)=x2+2x−3 to answer the question. The graph of the function f(x) as described in the problem passing through (negative 3, 0), (negative 1, negative 4) & (1, 0).© 2018 StrongMind. Created using GeoGebra. Which of the following domain restrictions allow an inverse function?There is more than one correct answer. Select all correct answers.

Answer 1

STEP - BY - STEP EXPLANATION

What to find?

Domain restrictions allow an inverse function.

Given:

Step 1

Determine the vertex of the function.

The vertex is (-1, 4)

Step 2

Using h =-1, it implies one of the restriction domain is x ≥ -1

Observe from the graph that, the other restriction domain is 0 ≤ x ≤ 3

ANSWER

x ≥ -1

0 ≤ x ≤ 3
