Step-by-step explanation:
4
f(- 4) = means what is the value of f(x) when x = - 4
locate x = - 4 on the x- axis, go vertically down to the graph at (- 4, - 1 )
that is f(- 4) = - 1
5
f(1) means what is the value of f(x) when x = 1
locate x = 1 0n the x- axis, go vertically down to the graph at (1, - 2 )
that is f(1) = - 2
6
f(x) = - 4 means what is the value of x when f(x) = - 4
locate - 4 on the vertical axis, go across to the right to the graph at (4, - 4 )
that is when f(x ) = - 4 then x = 4
