Answer:
g(x) = 2x – 3 is the function has an inverse that is also a function.
The correct option is A.
Inverse function;
The inverse of a function is the equation where x and y have switched places.
Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;
![y = \frac{x-3}{2}](https://tex.z-dn.net/?f=y%20%20%3D%20%5Cfrac%7Bx-3%7D%7B2%7D)
![y = \frac{1}{2} x - \frac{3}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20x%20-%20%5Cfrac%7B3%7D%7B2%7D)
k(x) = -
has the inverse x =
which simplifies to;
![y =\sqrt{ \frac{x}{-9} }](https://tex.z-dn.net/?f=y%20%3D%5Csqrt%7B%20%5Cfrac%7Bx%7D%7B-9%7D%20%7D)
f(x) = |x+2| is an absolute value function.
w(x) = -20 does not have an inverse which is a function.
Therefore
The function has an inverse that is also a function is g(x) = 2x – 3.

Step-by-step explanation:
here's your solution
Answer:
First you have to find x.
A stratight line is 180 degree.
Therefore, we have:
16x+8+4x-8=180
20x= 180
x= 9
Angle BAT = 16x+8= 16(9)+8= 152 degree.
Angle CAT= 180-152= 28 degree.
118 + 23 = 141
180 = Triangle
180 - 141 = 39
39 is the answer
6x-7+9x-8=90
15x=75
x=5
