Answer:
f(0) = - 4 , x = - 3
Explanation:
f(0) means what is the value of y when x = 0
x = 0 on the y- axis where the line has a value of - 4
f(0) = - 4
f(x) = - 2 means the y- value is - 2
locate y = - 2 on the y- axis, go horizontally across to meet the graph at
(- 3, - 2 )
so f(x) = - 2 , then x = - 3
