Q. Given f(x)=−x2−10x−15 f(x)=-x^{2}-10 x-15 , find f(2) f(2) \newlineAnswer:
  1. Given Function: Given the function f(x)=−x2−10x−15f(x) = -x^2 - 10x - 15, we need to find the value of f(2)f(2). This means we will substitute xx with 22 in the function and simplify.
  2. Substitute xx with 22: Substitute xx with 22 in the function:\newlinef(2)=−(2)2−10(2)−15f(2) = -(2)^2 - 10(2) - 15
  3. Calculate and Multiply: Calculate the square of 22 and multiply 1010 by 22:f(2)=−(4)−(20)−15f(2) = -(4) - (20) - 15
  4. Simplify Expression: Simplify the expression by performing the arithmetic operations: f(2)=−4−20−15f(2) = -4 - 20 - 15
  5. Final Result: Add the numbers together to get the final result:\newlinef(2)=−4−20−15=−39f(2) = -4 - 20 - 15 = -39
