The answer is option C) 19,-19
<u>Step-by-step explanation</u>:
Given, z² = 361
To eliminate the square of z, take square root on both sides
z = √361
- The factor of 361 could not be an even number, since the last digit of 361 is odd. So, eliminate option A)
- The option B) is a larger number and it cannot be the answer. So, eliminate it.
- Try option C) works or not. (19)² = 19
19 = 361 and (-19)² = -19
- Therefore, z = √361 = ±19. option C) is the correct answer.
For this case we have the following function:
We want to find the inverse of the function.
The first thing we should do is rewrite the function:
From here, we clear the value of x.
We have then:
Then, returning the variable changes, we have that the inverse function is:
Answer:
The inverse function of f (x) is:
