Q. Re-write the quadratic function below in Standard Formy=−(x−5)2+6Answer: y=
Question Prompt: Question prompt: What is the standard form of the quadratic function y=−(x−5)2+6?
Expand and Simplify: Expand the squared term in the quadratic function.To expand (x−5)2, we use the formula (a−b)2=a2−2ab+b2, where a=x and b=5.(x−5)2=x2−2×x×5+52=x2−10x+25
Multiply by −1: Multiply the expanded term by −1, as indicated by the negative sign in front of the parentheses.−1×(x2−10x+25)=−x2+10x−25
Add Constant Term: Add the constant term 6 to the result from Step 2 to complete the quadratic function in standard form.y=−x2+10x−25+6
Combine Like Terms: Combine like terms to simplify the quadratic function.y=−x2+10x−19
