Q. Use the following function rule to find f(1)f(1).\newlinef(x)=4x+5f(x) = 4^x + 5\newlinef(1)=f(1) = _____
  1. Plug in xx in f(x)f(x): Plug in 11 for xx in the function f(x)=4x+5f(x) = 4^x + 5.\newlinef(1)=41+5f(1) = 4^1 + 5
  2. Calculate 414^1: Calculate 414^1.\newline41=44^1 = 4
  3. Add 55 to 44: Add 55 to 44. \newlinef(1)=4+5f(1) = 4 + 5
  4. Calculate f(1)f(1): f(1)=9f(1) = 9
