Question

For what value of x is g(x) = -3?
x = 3

Answer 1

The value of x where g(x) = 3 is -4

How to find the value

The value is sought by tracing or drawing imaginary line on the graph.

Starting from the known value, g(x) = 3, draw the imaginary line to the graph.

Take note of the point of intersection between the imaginary line and graph

At this point, trace to the x-axis to get the corresponding point.

This gives the required value
