Q. Given the function f(x)=−23−x2, then what is f(x+2) as a simplified polynomial?Answer:
Substitute x+2: Substitute x+2 into the function f(x). We are given f(x)=−23−x2 and we want to find f(x+2). This means we need to replace every instance of x in the function with x+2. f(x+2)=−23−(x+2)2
Expand square term: Expand the square term in the expression.We need to square the binomial (x+2) to continue simplifying the expression.f(x+2)=−23−(x2+4x+4)
Distribute negative sign: Distribute the negative sign through the expanded square term.We will distribute the negative sign to each term in the expanded square to simplify the expression further.f(x+2)=−23−x2−4x−4
Combine like terms: Combine like terms, if any.In this case, there are no like terms to combine, so the expression is already simplified.f(x+2)=−23−x2−4x−4
