Answer: y = 7x²
<u>Step-by-step explanation:</u>
The general form of a quadratic equation is: y = a(x - h)² + k where
- "a" represents the vertical stretch
- "h" represents the shift to the left (or right)
- "k" represents the shift up (or down)
- (h, k) represents the vertex
Given the parent function y = x², a vertical stretch by a factor of 7 means the a-value is 7 ⇒ y = 7x²

I had this question on flocabulary.
Answer:
Step-by-step explanation:
Subtract 6 from both sides:.
Subtract 1/2n from both sides:
Multiply 2 on both sides:
Divide both sides by 5
Answer:
B
Step-by-step explanation:
To solve this, you need to combine like terms (ie. 6 and 9 or 2x and 3x).
4x + x - 3 - 9 + 4x = 6
9x - 12 = 6
