Which polynomial function could be represented by the graph below?
Svetllana [295]

Note that

1.

f(x)=x^3+x^2-6x=x(x^2+x-6)=x(x-2)(x+3)

The x-intercepts are at points x=-3, x=0, x=2. The graph should be increasing - decreasing - increasing.

2.

f(x)=x^3-x^2-6x=x(x^2-x-6)=x(x+2)(x-3)

The x-intercepts are at points x=-2, x=0, x=3. The graph should be increasing - decreasing - increasing.

3.

f(x)=-2x^3-2x^2+12x=-2x(x^2+x-6)=-2x(x-2)(x+3)

The x-intercepts are at points x=-3, x=0, x=2. The graph should be decreasing - increasing - decreasing.

4.

f(x)=-2x^3+x^2+12x=-2x(x^2-x-6)=-2x(x+2)(x-3)

The x-intercepts are at points x=-2, x=0, x=3. The graph should be decreasing - increasing - decreasing.

From the diagram you can see that x-intercepts are at points x=-3, x=0, x=2 and the graph is   decreasing-increasing-decreasing.

Answer: correct choice is 3.

Two different cross sections are taken parallel to the base of a three-dimensional figure. The two cross sections are the same s
iren2701 [21]

The geometric figures which could be this three-dimensional figure are:

  1. Cone
  2. Triangular pyramid
  3. Square pyramid

<h3>What is a cross section?</h3>

A cross section can be defined as an exposed surface or shape that is formed when a cut is made through a three-dimensional figure.

In this scenario, the geometric figures which could be this three-dimensional figure are:

  • <u>Cone</u>: when cut horizontally, its cross section would always form a circle of different sizes.
  • <u>Triangular pyramid</u>: when cut horizontally, its cross section would always form a triangle of different sizes.
  • <u>Square pyramid</u>: when cut horizontally, its cross section would always form a square of different sizes.
