Question

What is the equation of parabola that opens right, has a vertex at origin and a vertical stretch of 1/2?

Answer 1

what does "vertical stretch of 1/2" mean?

Answer 2

nvm can u help me with this one. Find the sum of x and y-coordinates of the vertex of the parabola given by equation 4x + 20 = (y - 7)2

Answer 3

(y-7) to the power of 2

Answer 4

if you write it in this form:
4a(x-h) = (y-k)^2

(h, k) is your vertex.

Answer 5

so factor out that 4 on the left:
4(x + 5) = (y - 7)^2

now tell me what is (h, k) ?

Answer 6

(-5,7)

Answer 7

good. that is your vertex... now you can answer the queston... :)

Answer 8

what is it?

Answer 9

2

Answer 10

great... :)

Answer 11

one more question please

Answer 12

What is the equation of the axis of symmetry of the parabola y2 - 3x - 10y + 13 = 0?
