Caleb is solving the following equation for xxx. x=\sqrt{x+2}+7x= x+2 ​ +7x, equals, square root of, x, plus, 2, end square root, plus, 7 His first few steps are given below. \begin{aligned}x-7&=\sqrt{x+2}\ \ \\ (x-7)^2&=(\sqrt{x+2})^2\\ \\ x^2-14x+49&=x+2 \end{aligned} x−7 (x−7) 2 x 2 −14x+49 ​ = x+2 ​ =( x+2 ​ ) 2 =x+2 ​ Is it necessary for Caleb to check his answers for extraneous solutions?

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

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.
