What polynomial has a graph that passes through the given points? (-2, 2) (-1, -1) (1, 5) (3, 67) A. y = -x3 + 4x2 + 2x - 2 B. y

= x3 + 4x2 + 2x - 2 C. y = x4 + 4x3 + 2x2 - 2x D. y = x3 - 4x2 - 2x - 2

An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points...

https://www.desmos.com/calculator

The alternate method is to subsitute each point into each equations...

I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2 y = 18 so (-2, 2) isn't on the curve.

so eliminate A

repeat the process with B etc is (-2, 2) in on the curve, then select the next point and check.

That's why graphing is easier
