Full solution

Q. Diketahui rumus fungsi f(x)=−1−xf(x)=-1-x, tentukan nilai f(−2)f(-2)
  1. Substitute xx with −2-2: Substitute xx with −2-2 in the function f(x)=−1−xf(x) = -1 - x.\newlinef(−2)=−1−(−2)f(-2) = -1 - (-2)
  2. Simplify the equation: Simplify the equation. f(−2)=−1+2f(-2) = -1 + 2
  3. Calculate the final value: Calculate the final value. f(−2)=1f(-2) = 1
