  • Solving composite functions

Solving the Question

We're given:


  • f(t)=4t-2

  • g(t)=2t+2

  • (3f-4g)(t)=?


(3f-4g)(t) is the same as
3f(t)-4g(t). Now, we can just plug in the functions as if they're variables in an equation.


3f(t)-4g(t)


= 3(4t-2)-4(2t+2)\\= 12t-6-8t-8\\= 4t-14

Answer


(3f-4g)(t)= 4t-14
