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

the reason you don't subtract the $4 is because it says "was" so the answer is $20
