Q. Given the function f(x)=5x2−4 f(x)=5 x^{2}-4 , then what is −f(x) -f(x) as a simplified polynomial?\newlineAnswer:
  1. Multiply by −1-1: We have f(x)=5x2−4f(x) = 5x^2 - 4. To find −f(x)-f(x), we multiply the entire function by −1-1.
  2. Distribute the negative sign: −f(x)=−(5x2−4)=−5x2+4-f(x) = -(5x^2 - 4) = -5x^2 + 4.
