16.06.2021 · Step 3: Interpret the Polynomial Curve. Once we press ENTER, an array of coefficients will appear: Using these coefficients, we can construct the following equation to describe the relationship between x and y: y = .0218x3 – .2239x2 – .6084x + 30.0915. We can also use this equation to calculate the expected value of y, based on the value of x.
