Question

The graph of a function g is shown below. Find g(- 2) and find one value of x for which g(x) = - 5

Answer 1

Answer:

$g\mleft(-2\mright)=-1$$g\mleft(0\mright)=-5$

Explanation:

Each point has two coordinates, the x-coodinate corresponds to the value of x (input value) and the y-coordinate corresponds to the value of that function f(x) (output value). The following image shows the coordinates used to find the values:

(-2,-1) and (0,-5)
