Use quadratic regression to find the equation of the parabola going through these 3 points, (2,-33), (4,5), (5,39) Y= ? x^2 + ? x + ? I just got the answer, it's y= 5x^2 + -11x + -31
​

c

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

[2, 2.5)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)
