The average prices of a gallon of fuel are shown in the table. Let p=f(t) be the average price of fuel at t years since 1980. The model f(t)=0.0075t2−0.2t+2.32 fits the data well. Year

a. Find the​ p-intercept of the model.
The​ p-intercept is nothing.
​(Type an ordered pair. Type an integer or decimal rounded to two decimal places as​ needed.)

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
