Convert the equation y= x2-2x-5 into vertex form. 

y= (x-1)2-6

y= -(x-1)2-6

y= (x+1)2-6

y= -(x+6)2-1

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Which of the following shows
f(x) = x2 + 12x - 2
written in vertex form?

f(x) = (x + 6)2 + 142

f(x) = (x + 6)2 - 34

f(x) = (x + 6)2 - 38

f(x) = (x + 6)2 + 34

Which of the following shows
f(x) = x2 - 8x + 1
written in vertex form?

f(x) = (x - 4)2 - 15

f(x) = (x - 4)2 + 17

f(x) = (x - 4)2 - 17

f(x) = (x - 4)2 + 65
