Question

On the graph below, for how many values does f(x) = 4? 5 + 5

Answer 1

When f(x) = 4, this means that the solution of the function, that is, the y values equals 4.

Hence, the question requires that we find the corresponding x values where y = 4.

On checking the graph, we can see that when y = 4, there are four different values of x.

These are approximately:

`x=-1,2,3.5,4.5`

Hence, there are 4 values where f(x) = 4.
