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

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

hi how are you doing today, if you need just ask me.

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
