Which of the following equations is of a parabola with a vertex at (1,2) answer choices 1. y=(x-1)^2 - 22 . y=(x-1)^ 2 + 23 . y=(x+1)^2 - 24 . y=(x+1)^2 + 2

ANSWER

The choice is correct.

EXPLANATION

The equation of a parabola in vertex form is given by:

where (h,k) is vertex of the parabola and 'a' is the leading coefficient of the parabola.

From the given options, the leading coefficient must be a=1.

We also have the vertex of the parabola at (1,2). This implies that h=1 and k=2.

We substitute these values into the formula to get,

The second option is correct.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

it will be a cylinder. with a diameter of 8 and 4 single pieces high
