Words to know

Write the letter of the definition next to the matching word as you work through the
lesson. You may use the glossary to help you.
midpoint

A. the point on a graph at which the graph
crosses the x-axis
quadratic function

B. in a parabola, the point at which the
function goes from increasing to
decreasing or vice versa
vertex

C. a point on a line segment that is
equidistant from the two endpoints
x-intercept

D. a second-degree polynomial function that
can be written in the form ax? + bx + c,
where a, b, and c are real constants and a
does not equal zero

Switch a with c and you are good. I think that is what you are asking?

Step-by-step explanation:

Step-by-step explanation:

A. The extreme point which can be the maximum or minimum is called the vertex.

B. Parabolas increase or decrease which refers to the maximum or minimum.

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.
