Use the graph to find(a) f(0) and (b) (f(-4)

Answer:
f(0) = 0 , f(- 4) = 2
Step-by-step explanation:
f(0) means what is the value of y when x = 0
From the graph this is the point (0, 0 ) , so
f(0) = 0
(b)
f(- 4) means what is the value of y when x = - 4
From the graph this is the point (- 4, 2 ) , so
f(- 4) = 2
