The vertex of this parabola is at (-5, -2). when the x-value is -4, the y-value is 2. what is the coefficient of the squared expression in the parabola's equation?

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
