Question

The graph of which quadratic equation is shown below?

Answer 1

y = x2 + 4x − 5

y = x2 − 4x − 5

y = −x2 + 4x − 5

y = −x2 − 4x − 5

Answer 2

The is a parabola with shape factor a = -1

Answer 3

plus one sorry

Answer 4

Can you factor?

Answer 5

yes

Answer 6

maybe better, do a (x-h)^2 = (y-k)^2

Answer 7

origin is -2,-9 correct?

Answer 8

y = x2 + 4x − 5

Answer 9

a(x-h)^2 = y -k wrong above sorry
(x + 2)^2 = x^2 + 4x + 4 = y + 9
you are correct

Answer 10

thank you

Answer 11

if you get the formula right :)
it's easy, just check the shape
