Answer: Option D
<u>Step-by-step explanation:</u>
Given equation:
First, we put hit and trial method to find out the one solution. So, if we put x=4 then the above expression will become zero. We can also write the above expression as
We know the formula, , make use of this, we get
So,
Hence, from the above expression, we have three values of x as x= 4, 2.64 and -2.64
Answer:
Step-by-step explanation:
(a) Rename h(x) as y
(b) Solve for x :
(d) Switch x and y
(e) Rename y as the inverse function
The graphs of inverse functions are reflections of each other across the line y = x.
In the diagram, the graph of h⁻¹(x) is the reflection of h(x) about the line y = x.
