You want to find out the better deal when renting a car, and you are comparing two rental companies . By pitting the variable and fixerd costs ,such as the cost per kilometer and hiring cost into an algebraic expression , then solving for the total cost ,you can see which company saves you money for differtent amount of driving . (Solve by graphical method ) Will mark you the brainliest please answer quickly

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
