Quick Math Question :)

Question

So for one of my pre0calc questions it shows me a graph and tells me to evaluate

a) f(-x) for x=-4

b) -f(x) for x=-6

-f(-x) for x=-4

-f(x+2) for x=0

and f(-x) + 4 for x=-6......so what exactly is it asking or wanting me to do ?

Answer 1

The graph is of f(x).

 

a) f(-x) for x = -4 is f(-(-4)) = f(4)

Look on the graph at x = 4 and find the value of y, that will be f(4).
