Question

What is the equation, in standard form, of a parabola that contains the following points? (1 point) (−2, 18), (0, 4), (4, 24) a. y = 2x2 − 3x + 4 b. y = −3x2 + 2x + 4 c. y = −4x2 − 3x – 2 d. y = −2x2 + 3x – 4

Answer 1

y = -2*3x - 1

Explanation:

The first term is -2 and the common ratio is 3 because every term is being multiplied by 3. The equation is y = -2*3x - 1.

Answer 2

It passes through the point (0,4) so y intercept is at y = 4 so the answer is either a or b as they fiinsh with + 4.

also when x = 4 y = 24 which satisifies equation a

Its a.
