Let f be a function such that f(-1) = 3 and f(2) = -4. The
coordinates of two points on the graph of y = 3f(-x) - 2
are ?

We just have to be very careful with our signs:

Start with



Substitute 1 for x





Substitute 3 for f(-1) since that is given







So one point is (x,y) = (1,7)

Again start with



Substitute -2 for x





Substitute -4 for f(2) since that is given







So another point is (x,y) = (-2,-14)
