A parabola has its vertex at (1,1) and passes through the point (-2,-2). Find the equation of this parabola.

a) y= -1/3 (x - 1)^2 + 1
b) y= 1/2 (x + 1)^2 - 3/2
c) y = 1/2 (x - 2)^2 - 2
d) y= 3(x - 1)^2 - 2

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
