Question

The graph of y=f(x)y=f(x) is shown below. Determine the value of xx when f(x)=2f(x)=2?

Answer 1

Graphs are used to represent functions, and functions are used to represented relations on a graph

The values of x are -1.4 and 1.4

The function of the graph is given as:

$y=f(x)$

When f(x) = 2, we have:

$y=2$

This can be written as:

$f(x)=2$

From the graph (see attachment), the x-values that corresponds to y = 2 are -1.4 and 1.4

Hence, the values of x are -1.4 and 1.4
