Use the graphing calculator to graph the quadratic function y = 2x2 + 2x – 40. what are the zeros of the function?
4 and –5
–4 and 5
–5 and –40
4 and –40

A. 4 and -5.

Step-by-step explanation:

Please find the attachment.

We have been given a quadratic function . We are asked to graph our given function and find the zeros of the function.

First of all, let us divide our polynomial by 2.

Now, we will factor our given function using splitting the middle term.

We can see from our attachment that the graph crosses x-axis at two points that are . Therefore, the zeros of the function are 4 and -5.

answer: 414,377,008
