Q. Given h(x)=−x−4 h(x)=-x-4 , find h(−2) h(-2) .\newlineAnswer:
  1. Substitute xx with −2-2: Substitute xx with −2-2 in the function h(x)=−x−4h(x) = -x - 4 to find h(−2)h(-2).
    h(−2)=−(−2)−4h(-2) = -(-2) - 4
    h(−2)=2−4h(-2) = 2 - 4
  2. Calculate the result: Calculate the result of 2−42 - 4 to find the value of h(−2)h(-2). \newlineh(−2)=2−4h(-2) = 2 - 4\newlineh(−2)=−2h(-2) = -2
