Q. Re-write the quadratic function below in Standard Formy=−5(x−2)2+3Answer: y=
Expand Squared Term: Expand the squared term (x−2)2.Reasoning: To write the quadratic function in Standard Form, we need to expand the squared term and then distribute the coefficient −5.Calculation: (x−2)2=x2−4x+4
Distribute Coefficient: Distribute the coefficient −5 to the expanded terms.Reasoning: Multiplying each term in the expansion by −5 will give us the quadratic in an expanded form.Calculation: −5(x2−4x+4)=−5x2+20x−20
Add Constant Term: Add the constant term +3 to the result from Step 2.Reasoning: To complete the quadratic function, we add the constant term to the expression obtained after distribution.Calculation: −5x2+20x−20+3=−5x2+20x−17
Write Final Function: Write the final quadratic function in Standard Form.Reasoning: The Standard Form of a quadratic function is ax2+bx+c. We have all the terms from the previous steps to write the function in this form.Calculation: y=−5x2+20x−17
