Question

Use the graphs of f and g shown below to find the values.

Answer 1

Find (g-f)

Answer 2

I dont remember how to do this?

Answer 3

pick a point on the x axis. look at the graph of g(x) at that point. read off the y value. now do the same for the graph of f(x) at that point. read off the y value. subtract the value from the f(x) graph from the g(x) graph. on another piece of paper, you make a graph, marking the value you just computed at the same value of x. repeat for as many points as needed.
