please i need help with this
Transportation The gas tank in Tony’s car holds 15 gallons, and the car can
travel 25 miles for each gallon of gas. When Tony begins with a full tank of gas, the
function f (x) = __1
25
x + 15 gives the amount of gas f(x) that will be left in the tank
after traveling x miles (if he does not buy more gas). Graph this function and give its
domain and range.

Best ResponseYou've already chosen the best response.0x must be nonnegative, since you can't travel a negative number of miles. y must also be nonnegative, since you can't have a negative amount of gas. Tony starts with 15 gallons when x=0, and this amount will decrease all the way down to zero, so the range is 0 <= f(x) <= 15. f(x) = 0 when 1/25x + 15 = 0, or 15 = x/25, so x = 15*25 = 375. Therefore the domain is 0 <= x <= 375.
