Activity
Bill's car gets 30 miles to the gallon. For every gallon of gas it consumes, his car runs 30 miles. Use this information to determine whether this
relation is a function.
Part b using the equation you found in part a substitute three different values for x. How many values of y do you get for each value of x? Type the values in the table

Part a:
It is a function, because the rate is constant!
Y=30x
Part b:
Let’s try with the most simple numbers, 2, 3, 4. Those are the numbers.

y=30(2) = y is 60.

y=30(3) = y is 90.

y=30(4) = y is 120.

I got one value of y for each value of x.

Values; 60, 90, 120.

Answer:

Part a: Bill’s car travels 30 miles per gallon of gas. If y represents the number of miles the car travels on x gallons of gas, the equation that represents this situation is y = 30x.

Part b:       gallons of gas (x) miles (y)

                                     1          30

                                     2  60

                                     3  90

Part c: There is no x-value that would lead to multiple y-values.

Part d: Yes, y = 30x is a function, because for every input, or x-value, there is only one output, or y-value.

All of the are edmentum answers. i would rephrase (:
