Mr. Yueng graded his students’ math quizzes. Students came up with four different answers when solving the equation x3 = 22. Which answer is correct? x=223 x=22−−√3 x=±22−−√3 x=22−−√

x = 22--√3

Step-by-step explanation:

For this case we must solve the following equation:

x³ = 22

If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:

3√x^3 = 3√22

x=3√22

That is the exact solution of the equation. Its decimal solution is given by:

x = 3√22 = 2.8020

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.
