Then
Finding p:
Re-write the quadratic function below in Standard Form y=-5(x+1)²+7
2 answers:
Answer: y = -5x² - 10x + 2
Step-by-step explanation:
<u>Given quadratic function</u>
y = -5 (x + 1)² + 7
<u>Given requirement</u>
Quadratic Standard Form: y = ax² + bx + c
<u>Simplify the exponents</u>
y = -5 (x + 1) (x + 1) + 7
y = -5 (x² + x + x + 1) + 7
y = -5 (x² + 2x + 1) + 7
<u>Expand the parenthesis by distributive property</u>
y = (-5) · x² + (-5) · 2x + (-5) · 1 + 7
y = -5x² + (-10x) + (-5) + 7
y = -5x² - 10x - 5 + 7
<u>Combine like terms</u>
Hope this helps!! :)
