Let x = hours of service.
Let y = total charges for x hours
The fixed charge is $20.
The charge per hour is $20.
Brock's charges for x hours is
y = 40 + 20x
This is a straight line with slope = 20 and y-intercept = 40.
The correct graph is W.

Answer:
B (second table in list)
Step-by-step explanation:
The function is a quadratic with vertex and y-intercept at (0,-2). The parabola opens up meaning only y - values above -2 are a part of the function. Since range is the set of all y values, then the range is .
The domain is not restricted and it is all real numbers.
The inverse of the function is where x and y are switched. So the range becomes the domain and vice verse.
This means the domain of the inverse is and the range of the inverse is all real numbers.
