GRADES A professor announces that course grades will be computed by taking 40% of a student's project score (0-100 points) and adding 60% of the
student's final exam score (0-100 points). If a student gets an 86 on the project,
what scores can she get on the final exam to get a course grade of at least 90?

how do you solve this?

a - base

b - exponent

so,

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.
