Sketching Polynomial Functions

Sketching Polynomial Functions 1.23 - Solution

arrow_back Return to Sketching Polynomial Functions

Let's start with analyzing the given function. The degree of the polynomial is so the function is quadratic. Thus, the graph of the function is a parabola. Out of the given graphs, only IV shows a parabola. What is more, the leading coefficient is which is negative, so the ends of the function must go downwards. This is also true for the graph IV, so it is the answer.
