If the point (0, 20) is the y-intercept of the parabola with the vertex is (8, -12), What is the equation for this parabola.

Step-by-step explanation:

f(x) = a(x - h)² + k            - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (8, -12) is

f(x) = a(x - 8)² - 12  

The point (0, 20) is the y-intercept means if x=0 then f(x)=20

20 = a(0 - 8)² - 12 

20 +12 = 64a - 12 +12

32 = 64a

a = ³²/₆₄ = ¹/₂

Therefore the equation (in vertex form) of parabla is:

                                  f(x) = ¹/₂(x - 8)² - 12  

the answer is (-4,-4)

hope this ! : d

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
