Answer:
y=3sqrt(x)
x≥0
Step-by-step explanation:
The domain of a function refers to all values of x for which y is defined.
Since this is a square root function, we need to keep the expression under the square root sign to be greater than or equal to zero.
As soon as the expression under the root sign is less than zero, the function will not be defined.
This means that the square root of a negative number will not be a real number.
Answer: The inverse of the given function is 
Step-by-step explanation: We are given to find the inverse of the following linear function :
The inverse of y = f(x) is written as
Substituting the above in equation (i), we get
Thus, the inverse of the given function is
First you have to solve the equation inside the parentheses. (5 + 3) = 8. Then you multiply,
6 • 8 = 48. After that just divide 48 by 2 and the answer is 24. Hope this helped.
