Answer:
A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function

Answer:
Width: 10.5 feet
Length: 31.5 feet
Step-by-step explanation:
Let x represent width of the concrete slab.
We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be
.
We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:




Now, we will take square root of both sides.


Therefore, the width of slab is approximately 10.5 feet.
The length of the slab would be
.
Therefore, the length of slab is approximately 31.5 feet.
