Q. Use the following function rule to find f(187) f(187) .\newlinef(x)=−2x−43f(x) = -2 \sqrt{x-43}\newlinef(187)=□f(187) = \square
  1. Plug xx into function: First, we need to plug x=187x = 187 into the function.\newlinef(187)=−2187−43f(187) = -2\sqrt{187 - 43}
  2. Subtract from 187187: Now, subtract 4343 from 187187.\newlinef(187)=−2(144)f(187) = -2\sqrt{(144)}
  3. Find square root of 144144: Next, find the square root of 144144. f(187)=−2144f(187) = -2\sqrt{144} f(187)=−2×12f(187) = -2 \times 12
  4. Multiply by −2-2: Finally, multiply −2-2 by 1212 to get the answer.\newlinef(187)=−2×12f(187) = -2 \times 12\newlinef(187)=−24f(187) = -24
