Q. Use the following function rule to find f(3)f(3).\newlinef(x)=7(8)x+12f(x) = 7(8)^x + 12\newlinef(3)=f(3) = _____
  1. Identify Function: Identify the function which represents f(3)f(3). Substitute in 33 for xx in f(x)=7(8)x+12f(x) = 7(8)^x + 12. f(3)=7(8)3+12f(3) = 7(8)^3 + 12
  2. Substitute and Calculate: Evaluate 7(8)37(8)^3.\newline7(8)37(8)^3\newline=7×8×8×8= 7 \times 8 \times 8 \times 8\newline=7×512= 7 \times 512\newline$= \(3584\)
  3. Evaluate Expression: Determine the value of \(f(3)\).\(f(3) = 3584 + 12\)\(f(3) = 3596\)
