I have a graph that looks like a C its a parabola and it has a vertex of -2,0 My question says to evaluate f(2) f(-2) f^-1(0) and f^-1(2) how do I do this? I sketched the inverse already now what? Please help me
HallsofIvy said:Darned if I know! You will need to know more about the function than just that its graph "looks like a C its a parabola and it has a vertex of -2,0". From that, you can only say that f-1(0)= -2 since the inverse function swaps x and y values.
f(2) and f-1 depend upon other information about the graph.
