Example: Exact Polynomials with Known Coefficents


When you need to find points from a known polynomial, you can enter the coefficients of each term into the Exact Polynomials program and find a y value for any x value.


Example

Find the values of y when x is 1, 2, 2.5, and 4 for the polynomial y = 1 + 2x + 3x2 + x3.
