The gas tank in a car holds a total 16 gallons of gas. the car travels 75 miles on 4 gallons of gas. if the gas tank is full at the beginning of a trip, which graph represents the rate of change in the amount of gas in the tank ?

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.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

f(x)=2/3x-8, which give g(x) the greatest value.
