Full solution

Q. Use the following function rule to find f(6)f(-6).\newlinef(x)=5x2f(x) = 5|x| - 2\newlinef(6)=f(-6) = _____
  1. Identify x value: Step 11: Identify the value of xx and substitute it into the function.\newlinef(-6)=5-62f(\text{-}6) = 5|\text{-}6| - 2
  2. Calculate absolute value: Step 22: Calculate the absolute value of 6–6.6=6|–6| = 6
  3. Substitute absolute value: Step 33: Substitute the absolute value back into the function.\newlinef(6)=5×62f(-6) = 5 \times 6 - 2
  4. Perform multiplication and subtraction: Step 44: Perform the multiplication and subtraction to find f(6)f(–6).f(6)=302=28f(–6) = 30 - 2 = 28
