Understanding Polynomial Intercepts

The video tutorial explains how to find the intercepts of a polynomial function D of T = 8T^4 - 36T^3 - 22T^2. It covers the process of determining the D intercept by setting T to 0 and evaluating the function, resulting in the origin (0,0). The tutorial also details finding T intercepts by setting the function to zero and solving the equation through factoring, yielding intercepts at (0,0), (-1/2,0), and (5,0). The video concludes with a verification of these intercepts using graph analysis.

What is the polynomial function D of T given in the video?

• D of T = 8T^2 - 36T - 22

• D of T = 8T^4 - 36T^3 - 20T^2

What is the significance of the point (0,0) in the context of the function D of T?

• It is a T intercept

• It is neither a D nor T intercept
