What are the steps for using integer tiles to evaluate the expression 45-15? O Start with 15 ties and separate them into 3 same-sized groups
O Seart with 45 tles and separate them into 15 same-sized groups
O Assemble 45 groups of 3 tiles each
O Assemble 45 groups of 15 tiles each

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

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.
