Q. Re-write the quadratic function below in Standard Formy=−(x+2)2+1Answer: y=
Expand Squared Term: Expand the squared term in the equation y=−(x+2)2+1. To expand (x+2)2, we use the formula (a+b)2=a2+2ab+b2. Here, a=x and b=2, so (x+2)2=x2+2×x×2+22.
Calculate Expanded Form: Calculate the expanded form of (x+2)2.(x+2)2=x2+4x+4
Substitute into Equation: Substitute the expanded form of (x+2)2 into the original equation.y=−(x2+4x+4)+1
Distribute Negative Sign: Distribute the negative sign to each term inside the parentheses.y=−x2−4x−4+1
Combine Constant Terms: Combine the constant terms −4 and +1.y=−x2−4x−3
