The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exercising.
The function g(x) = 2x + 125 represents the calorie deficit that occurs when following a particular diet, where x is the number of hours spent exercising.

What is (f + g)(3)? Show all work and explain your answer.

Note: Check your work when adding.

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)   (by definition)

then

(f + g)(3) = f(3) + g(3)

             = 2(3) + 210 + 2(3) + 125

             = 6+210+6+125

             =347
