Answer:
X=10
Step-by-step explanation:
Plug 3 into the k in the first equation. Multiply by 3 to cancel out the fraction. This leaves you with x-1=9. Add 1 to both sides and you get x=10.
Answer:
Domain [-5,∞)
Range [0,∞)
Step-by-step explanation:
Part 1) Find the domain
we have

we know that
The radicand must be greater than or equal to zero
so

solve for x
subtract 5 both sides

The solution for x is the interval [-5,∞)
All real numbers greater than or equal to -5
Remember that
The domain of a function is the set of all possible values of x
therefore
The domain of the function f(x) is the interval [-5,∞)
Part 2) Find the range
we have

Find the value of f(x) for the minimum value of x
For x=-5


The minimum value of f(x) is equal to zero
so
The solution for f(x) is the interval [0,∞)
All real numbers greater than or equal to 0
Remember that
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
therefore
The range of the function is the interval [0,∞)
