Question

Write the quadratic function in vertex form.

y = x2 - 2x + 5

Answer 1

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

Answer 2

@surdawi Can you help me solve it. I kind of forgot how to do it.

Answer 3

-b/2a then put the answer into the x values to get y

Answer 4

h=-b/(2a)

Answer 5

@surdawi ?????

Answer 6

@zeesbrat3 what?

Answer 7

y = x2 - 2x + 5
y = ax2 - bx + c

Answer 8

@surdawi H=-1?

Answer 9

show me how?

Answer 10

@surdawi -2/2(1)
=-2/2
=-1

Answer 11

its -b = -(-2) =2

Answer 12

@surdawi so its just 1

Answer 13

yes

now plug the 1 for x and solve for y
y = x2 - 2x + 5

Answer 14

@surdawi y=(1)^2-2(1)+5
=1-2+5
=4

Answer 15

h = 1
k = 4

now plug that in to the equation i sent earlier

Answer 16

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

Answer 17

yes
