Question

Which equation has this graph?


A. y = x2 - 6x + 5
B. y = -x2 - 6x + 5
C. y = -x2 - 6x - 5
D. y = x2 + 6x - 5 Which equation has this graph?


A. y = x2 - 6x + 5
B. y = -x2 - 6x + 5
C. y = -x2 - 6x - 5
D. y = x2 + 6x - 5 @Mathematics

Answer 1

y=(x-3)^2-4

Answer 2

It opens up so the x^2 term is positive. This leaves A and D. Next it goes through the point (0, 5) so it has to be A.

Answer 3

Ooops didn't see the choices. If you expand mine,
x^2-6x+9-4
x^2-6x+5

Answer 4

The parabola equation y=x^2
Here y=y+4 and x=x-3
so y+4 = (x-3)^2
solving, y=x^2-6x+5
Answer is A
