The inverse function of g(x) is:
So the correct option is D.
<h3>How to get the inverse of g(x)?</h3>
Here we have the function:
Remember that two functions f(x) and g(x) are inverses if:
Then we must have:
Solving for f(x), we get:
Then the correct option is D.

Answer:
<em>120 degrees</em>
Step-by-step explanation:
Find the diagram attached.
From the diagram;
Interior angles are m∠BCA and m∠ABC
Exterior angle is m∠DAB
The sum of interior angle of the triangle is equal to exterior
m∠BCA +m∠ABC =m∠DAB
Given
m∠ABC = 70
m∠BCA =50
m∠DAB = 70 + 50
m∠DAB = 120 degrees
<em>Hence the measure of m∠DAB is 120 degrees</em>
