Answer:
1 and - 2
Explanation:
f(0) is asking what is the value of y when x = 0
locate x = 0 ( the origin), go vertically up the y- axis to meet the line at (0, 1)
then f(0) = 1
f(x) = 5 is asking what is the value of x when y = 5
locate y = 5 on the y- axis, go horizontally across to meet the line at (- 2, 5 )
then f(x) = 5 when x = - 2
