The cost C(x), where x is the number of miles driven, of renting a car for a day is $26 plus $1.75 per mile. What is the slope of the linear function and its units? (dollars per mile, dollars, miles per dollar, or miles) - select the correct units What is the y-intercept and its units? (miles or dollars) - select the correct units What is the linear function, C(x)? C(x)=

Is there more to the question?

The correct answer is .44

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
