Rewrite each equation in the form of y= ax to the power of 2 + bx + c. Tell whether the equation represents a quadratic function.
1. y=2x- (-4) - 5× + 2
2. y= 4 (x to the power of 2 + 2)
3. y + 2 = -3(x to the power of 2 + 2x) -2x to the power of 2

step-by-step explanation:

the pictures.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
