The image of triangle CDE after a rotation of 90º counterclockwise around the origin is graphed at the end of the answer.

<h3>What is a rotation?</h3>

When a polygon undergoes a rotation, this rotation is over an angle measure, that defines the coordinate rule for each vertex of the polygon.

For triangle CDE, the vertices are given as follows:

D(-7,-1), C(-7,-7), E(-4,-8).

The rule for a rotation of 90º counterclockwise around the origin, for each vertex (x,y) of the polygon, is given by:

(x,y) -> (-y,x).

Hence, applying the rule above, the vertices of the image of triangle CDE will be given as follows:

D'(1,-7), C'(7,-7), E'(8,-4).

The triangle, with these vertices labeled, is graphed at the end of the answer.

The graphs below have the same shape.What is the equation of the red graph ?
Sindrei [870]

Answer:

B. G(x) = x³ - 5

Step-by-step explanation:

The graphs below are the same shape. They share the same formula but different y-intercepts.

F(x) = x³ has a y-intercept of 0.

F(x) = x³ + 0

G(x) has a y-intercept of -5.

G(x) = x³ - 5
