MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER From the graphs of f and g in the figure, we find the following. (Assume that each point lies on the gridlines.) (f+g)(-1) = (f-g)(-1) = (fg)(-1) = ()(-1) = Need Help? 0 Read It g x 2. [-/2 Points] DETAILS SPRECALC7 2.7.002. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER By definition, (fog)(x) = ? Need Help?
