Question

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)(1)? Explain.
339 calories burned while dieting for 1 hour.

339 calories burned while combining diet with 1 hour of exercise.

212 calorie calories burned when combining diet with 1 hour of exercise.

212 calories burned while exercising for 1 hour.

Answer 1

Given the functions as:

f(x)=2x+210  

g(x)=2x+125

(f+g)(x) = 2x+210 +2x+125 = 4x +335

(f+g)(1) = 4(1)+335

          =339

339 calories burned while combining diet with 1 hour of exercise

Answer 2

This means 339 calories burned while combining diet with 1 hour of exercise

Step-by-step explanation:

Given the functions as:

f(x)=2x+210  

g(x)=2x+125 then

(f+g)(x) = 2x+210 +2x+125 = 4x +335

(f+g)(1) = 4(1)+335

           =339

This means 339 calories burned while combining diet with 1 hour of exercise
