Q. Use the following function rule to find f(1)f(1).\newlinef(x)=12x+3f(x) = 12^x + 3\newlinef(1)=f(1) = _____\_\_\_\_\_
  1. Substitute xx in function: Substitute 11 for xx in the function f(x)=12x+3f(x) = 12^x + 3.\newlinef(1)=121+3f(1) = 12^1 + 3
  2. Calculate 12112^1: Calculate 12112^1.\newline121=1212^1 = 12
  3. Add 33 to result: Add 33 to 1212.\newlinef(1)=12+3f(1) = 12 + 3
  4. Final result: f(1)=15f(1) = 15
