Andrea bought tacos from a food truck and left a 25\%25%25, percent tip of \$2.00$2.00dollar sign, 2, point, 00.

Given the graph below state whether or not the relation is a function, and give the domain and range.

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?

Could somebody me with this radical simplification?
