We are given the graph of function g, the parabola.
g(a)=b means that the pair (a, b) in a point on the graph.
So we check the following points, whether they are on the graph or not:
(1, -1) not on graph so g(1) = -1 Not true
(0, 0) on graph so g(0) =0 True
(4, -2) not on graph so g(4) = -2 Not true
(1, 1) on graph so (1)= 1 True
(-1, 1) on graph so g(-1)= 1 True
(4, 2) not on graph so g(4)= 2 Not true
Answer:
g(0) =0
g(1) = 1
g(-1) =1
