For a complex number written in polar form, its representation is unique as long as the argument is restricted to [0, true or false

False

Step-by-step explanation:

i = (1, π/2) = (-1, 3π/2) . . . . the same complex number written 2 ways in polar form.

The representation is unique if the "radius" is required to be positive.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

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.
