The mistake is that they subtracted 21 instead of adding it. you would have had to added 21 to the left side to cancel it out and added 21 to the right side to get p= 55

Determine the equation of the graph shown y = a(x - h)^2 + k
LUCKY_DIMON [66]

Answer:

y=-(x+1)^2+4

Step-by-step explanation:

we know that

y=a(x-h)^2+k

Is the equation of a vertical parabola written in vertex form

where

(h,k) is the vertex

a is the leading coefficient

In this problem we have

The vertex is the point (-1,4)

so

(h,k)=(-1,4)

substitute

y=a(x+1)^2+4

Find the value of a

we have the ordered pair (0,3)

substitute the value of x and the value of y in the quadratic equation and solve for a

3=a(0+1)^2+4

3=a+4\\a=3-4\\a=-1

therefore

y=-(x+1)^2+4
