the function f(x) = 2x + 510 represents the number of calories burned when exercising, where x is the number of hours spent exercising.
the function g(x) = 200x − 125 represents the calorie deficit that occurs when combining diet with exercise, where x is the number of hours spent exercising.
what is (f + g)(1)? explain.
512 calories burned while exercising for 1 hour
587 calories burned while exercising for 1 hour
512 calories burned while combining diet with 1 hour of exercise
587 calories burned while combining diet with 1 hour of exercise
