Answer :

The point on the graph y = -f(x) is (-2 , -8)

According to the question the coordinates we have been given is (-2 , 8) and it is on the graph y = f(x)

That is we have been given that

                f(-2) = 8            (1)

Now we have to find the point on the graph y = -f(x)

So we will choose the value of x = -2 in f(x)

 Thus, putting the required value we get

                y = - f(-2)

As the value of f(-2) is 8 from equation (1). we will equate the value in the above equation we get

               y = -(8)

               y = -8

Hence the point on the graph is (-2 , -8)
