Question

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

Answer 1

one approach
your x values are (-2, -1, 1, 3 )
for each function use the x value and find the y value
does it match the y value given?

Answer 2

I've tried that but the y values don't match.

Answer 3

for all of them?

Answer 4

let do it together
