Answer:
B. 2 is your answer
Step-by-step explanation:
You will use the slope formula to find the slope of the equation.
(3, 7) and (-2, -3) will be used.
7 and -3 are your y's. 3 and -2 are your x's.
(7 - (-3))/(3 - (-2)) = 10/5 = 2
B. 2 is your answer
Answer:
![\boxed{\boxed{y = 7(x+3)^2-63}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7By%20%3D%207%28x%2B3%29%5E2-63%7D%7D)
Step-by-step explanation:
The general vertex form of parabola is,
![y=a(x-h)+k](https://tex.z-dn.net/?f=y%3Da%28x-h%29%2Bk)
where,
(h, k) is the vertex of the parabola.
The given function is,
![\Rightarrow f(x) = 7x^2 + 42x](https://tex.z-dn.net/?f=%5CRightarrow%20f%28x%29%20%3D%207x%5E2%20%2B%2042x)
![\Rightarrow y = 7x^2 + 42x](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207x%5E2%20%2B%2042x)
![\Rightarrow y = 7(x^2 + 6x)](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207%28x%5E2%20%2B%206x%29)
![\Rightarrow y = 7(x^2 + 2\cdot x\cdot 3)](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207%28x%5E2%20%2B%202%5Ccdot%20x%5Ccdot%203%29)
![\Rightarrow y = 7(x^2 + 2\cdot x\cdot 3+3^3-3^2)](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207%28x%5E2%20%2B%202%5Ccdot%20x%5Ccdot%203%2B3%5E3-3%5E2%29)
![\Rightarrow y = 7(x^2 + 2\cdot x\cdot 3+3^3)-7\cdot 3^2](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207%28x%5E2%20%2B%202%5Ccdot%20x%5Ccdot%203%2B3%5E3%29-7%5Ccdot%203%5E2)
![\Rightarrow y = 7(x+3)^2-7\cdot 9](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207%28x%2B3%29%5E2-7%5Ccdot%209)
![\Rightarrow y = 7(x+3)^2-63](https://tex.z-dn.net/?f=%5CRightarrow%20y%20%3D%207%28x%2B3%29%5E2-63)
This is vertex form the given function.
