Q. Use the following function rule to find f(2r)f(2r). Simplify your answer.\newlinef(k)=−8kf(k) = -8k\newlinef(2r)=f(2r) = ______
  1. Identify function rule: Identify the function rule and the input value.\newlineThe function rule given is f(k)=−8kf(k) = -8k, and we need to find the value of f(2r)f(2r).
  2. Substitute input value: Substitute the input value into the function rule.\newlineReplace kk with 2r2r in the function rule to get f(2r)=−8(2r)f(2r) = -8(2r).
  3. Simplify expression: Simplify the expression.\newlineMultiply −8-8 by 2r2r to get f(2r)=−16rf(2r) = -16r.
