The table below shows the outputs y for different inputs x: input (x) 1 1 3 3 output (y) 4 2 12 6 part a: does the table represent y as a function of x? justify your answer. (5 points) part b: the total cost f(x), in dollars, for renting a paddleboat for x hours is shown below: f(x) = 20 10x what is the value of f(120), and what does f(120) represent? (5 points

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
