Answer:
g(x) is the reflection of f(x) through the y-axis.
Step-by-step explanation:
Given : Functions and
To find : How are the two functions related to each other?
Solution :
When we examine the two function,
and
We see that x-coordinate in g(x) is negative which signifies that it will be reflected through y-axis.
Therefore, the functions are related to each other as g(x) is the reflection of f(x) through the y-axis.

Answer:
26 ft height
Step-by-step explanation:
The distance between the streetlamp and the tip of his shadow is 9 + 13 = 22 ft.
A rectangle triangle is formed in which one side is 22 ft long and the other side is the streetlamp height. The angle between the 22 ft side and the hypotenuse is 50°. From tangent definition:
tan(50°) = (streetlamp height)/(22 ft)
tan(50°) * (22 ft) = streetlamp height
26 ft = streetlamp height
