Answer:
Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.

graphically you can check this if it seems that the functions are reflected over the line x=y.

Answer: D
Step-by-step explanation:
When you convert the equation to y-intercept form it becomes y >
x +3 and the sign is > because the line is dotted and the shaded portion is above the graph.
The length of the image of the segment CD is 10 units if the segment CD has endpoints at C(0, 3) and D(0, 8).
<h3>What is a distance formula?</h3>
It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:

We have two points C(0, 3) and D(0, 8)
The distance between these two points:
d = √(8-3)²
d = 5 units
The length of the image of segments CD = dilation factor×length of CD
= 2×5
= 10 units
Thus, the length of the image of the segment CD is 10 units if the segment CD has endpoints at C(0, 3) and D(0, 8).

Step-by-step explanation: The square root of 3 is the positive real number that, when multiplied by itself, gives the number 3. It is more precisely called the principal square root of 3, to distinguish it from the negative number with the same property. It is denoted by √3. The square root of 3 is an irrational number.
