Mr. hermans's class is selling candy for a school fundraiser. their goal is to raise $500 by selling c boxes of candy. for every box of candy they sell, they earn $2.75. write and equation that the students could solve to figure out how many boxes they need to sell. answer quickly.

2.75c ≥ 500

c ≥ 500 / 2.75

c ≥ 181.82

it should be greater than 181.82 to reach and get the target

So c should be like 182, 183, 184, and above

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
