Q. Re-write the quadratic function below in Standard Formy=4(x−4)2−7Answer: y=
Expand Squared Term: Expand the squared term (x−4)2.Reasoning: To write the quadratic function in Standard Form, we need to expand the squared term and simplify.Calculation: (x−4)2=x2−2×(4)×x+42=x2−8x+16
Multiply by Coefficient: Multiply the expanded term by the coefficient 4. Reasoning: The quadratic function has a coefficient of 4 that needs to be distributed to each term in the expanded squared term. Calculation: 4∗(x2−8x+16)=4x2−32x+64
Subtract Constant: Subtract 7 from the result of Step 2.Reasoning: The quadratic function includes a constant term −7 that needs to be combined with the result from Step 2 to complete the Standard Form.Calculation: 4x2−32x+64−7=4x2−32x+57
Write Standard Form: Write the final Standard Form of the quadratic function.Reasoning: After expanding, distributing, and combining like terms, we have the quadratic function in Standard Form.Calculation: y=4x2−32x+57
