Q. If f(x)=x26x8 f(x)=x^{2}-6 x-8 , what is the value of f(2) f(-2) ?\newlineChoose 11 answer:\newline(A) 16-16\newline(B) 10-10\newline(C) 00\newline(D) 88
  1. Step 11: Evaluate the function: We need to evaluate the function f(x)=x26x8f(x) = x^2 - 6x - 8 at x=2x = -2.\newlineTo do this, we substitute xx with 2-2 in the function and simplify.\newlinef(2)=(2)26(2)8f(-2) = (-2)^2 - 6(-2) - 8
  2. Step 22: Substitute xx with 2-2: Now we calculate the value step by step.\newlineFirst, we calculate (2)2(-2)^2 which is 44.\newlineThen we calculate 6-6 times 2-2 which is 1212.\newlineFinally, we subtract 88 from the sum of 44 and 1212.\newline2-200
  3. Step 33: Simplify the expression: We add 44 and 1212 to get 1616, and then subtract 88 from 1616.\newlinef(2-2) = 16816 - 8
  4. Step 44: Calculate (2)2(-2)^2: Subtracting 88 from 1616 gives us 88.\newlinef(2-2) = 88
