(x + y + 2)(y + 1)
what is equivelnt to this?

y²+xy+x+3y+2.

Step-by-step explanation:

Given that,

(x + y + 2)(y + 1)

We will multiply the first bracket variable with the second bracket variable.

i.e, the x with y+1, and the y with y+1, and 2 with y+1.

Therefore,

x(y+1)+y(y+1)+2(y+1)

xy+x+y²+y+2y+2

Collecting like terms and rearranging

y²+xy+x+y+2y+2

y²+xy+x+3y+2 Answer

what are the statements

step-by-step explanation:

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.
