Answer:

1. The number of wheels in the parking lot is based on the number of cars in the parking lot.

B) Yes, because the number of wheels is specific to the number of cars in the parking lot. Because each car has four wheels. So, the wheels are  dependent on cars.

2. We can see the dots on each axis. These are like :

C) {(–5, 4), (–2, –1), (–1, 3), (4, –3)}

3. D) An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph. For each input there is an output.

4. The expression is :

y=3x^{2} +1

When input or x = 4

So, y=3(4)^{2} +1

=>y=(3times16) +1

=y=48+1

=> y=49 (option C)
