Q. Use the following function rule to find f(3)f(3).\newlinef(x)=8x+10f(x) = 8^x + 10
  1. Substitute xx in function: Substitute 33 for xx in the function f(x)=8x+10f(x) = 8^x + 10.\newlinef(3)=83+10f(3) = 8^3 + 10
  2. Calculate 838^3: Calculate 838^3. \newline83=8×8×88^3 = 8 \times 8 \times 8\newline=64×8= 64 \times 8\newline=512= 512
  3. Add 1010 to result: Add 1010 to 512512.\newlinef(3)=512+10f(3) = 512 + 10\newline=522= 522
