Bill makes car payments of $273/month for the next 3 years. His car loan has an interest rate of 2.6%, discounted monthly.

What was the initial price of the car?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

as before, graphs and tables allow us to estimate at best.

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.
