Without graphing, state the vertex for each of the following quadratic equations.
Elena L [17]

Answer:

(5,3)

(0,-2.5)

(-4,0)

Step-by-step explanation:

The equation of a parabola in the form of the vertex is the following:

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

and the vertex will be in the coordinates: (h,k)

for a. y = (x - 5)^2 + 3

we can see that h=5, and k=3

so the vertex is at (5,3)

for b. y =x^2 - 2.5

we can re accommodate this equation as: y=(x-0)^2+(-2.5)

in this form is easier to see that h=0, and k=-2.5

so the vertex is at (0,-2.5)

for c. y = (x + 4)^2

we can re accommodate this equation as: (x-(-4))^2+0

and as we can see h=-4 and k=0

so the vertex is at (-4,0)
