Q. Use the following function rule to find f(2)f(2).\newlinef(x)=4xf(x) = 4^x\newlinef(2)=f(2) = _____
  1. Identify Function: Identify the function which represents f(2)f(2).\newlineSubstitute in 22 for xx in f(x)=4xf(x) = 4^x.\newlinef(2)=42f(2) = 4^2
  2. Substitute in 22: Evaluate 424^2.
    424^2
    =4×4= 4 \times 4
    =16= 16
