Answer:
B
Step-by-step explanation:
Two negatives is a positive, and you want your outcome to be a positive x, therefore b is the correct answer.
Given :
Three roots ,
.
To Find :
A cubic function with the given zeros.
Solution :
Equation of polynomial of 3 zeroes is given by :

Therefore, the cubic function of given zeroes is
.
Hence, this is the required solution.
The answer is $.085. This is the cost of the gasoline per mile. I got the answer through adding all the expenses (insurance, registration, and maintenance) which added up to $1191 and then subtracting it from $1837, which gets me $646. Lastly, I computed for the cost of gasoline per mile through dividing $646 by 7600 miles. I got .085.
The slope is 1.5, and the y-intercept is -2.
Remember the equation y = mx + b
