Simplify the following algebraic expressions: (a) a×a×a (b) 7b+5b−3a (c) 6m−2+3m (d) 8y÷4 (e) 6a+2b−3a+6

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.
