Which mapping diagram corresponds to the ordered pairs (1,2)\(\left\)(1,2\(\right\)), (3,4)\(\left\)(3,4\(\right\)), and (1,5)\(\left\)(1,5\(\right\))?
Find the domain of the function y=1x−2y=\(\frac{1}{x-2}\).
Find the domain of y=x+1x−2y=\(\sqrt{\frac{x+1}{x-2}\)}. Express your answer in interval notation.
Find a linear rule y=mx+by = mx + b that fits the ordered pairs (1,4)(1,4) and (3,10)\(\left\)(3,10\(\right\)). Then, determine whether the pair (2,7)(2,7) lies on that same line.
