Answer:
Explanation:
The symbol f(6) refers to the value of the function f at x = 6. It's the y-coordinate on the graph of f at x = 6. Go to 6 on the x-axis, then go down to the graph of f (blue). What do you see as the y-coordinate? I counted down the squares and got -6.
The symbol g(5) refers to the y-coordinate on the graph of function g (purple dotted). Go to 5 on the x-axis and count down until you hit the graph of g. I got -5.
Now plug those two values into the expression in the problem.
