Use the graphing calculator to graph the quadratic function y= 2x + 2x- 40. What are the zeros of the function? O 4 and-5
O4 and 5
O-5 and40
04 and-40

The answer is 4 and -5.

Step-by-step explanation:

Working under the assumption that the first term is not 2x, but 2x²,  you can find the zero values by factoring the expression:

With it factored we can see that x being equal to -5 or 4 will give a zero value

Let's also see it plotted, as the question said to use a graphing calculator:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
