Part of the graph of the function f(x) = (x – 1)(x + 7) is shown below. which statements about the function are true? select three options.
the vertex of the function is at (–4,–15).
the vertex of the function is at (–3,–16).
the graph is increasing on the interval x > –3.
the graph is positive only on the intervals where x < –7 and where x > 1.
the graph is negative on the interval x < –4.

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.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
