1) Which of the equivalent expressions for P(x) reveals the price which gives a profit of
zero without changing the form of the expression?
a)
b)
P(x) = -3x2 + 432x - 1680
P(x) = -3(x - 4)(x - 140)
P(x) = -3(x - 72)2 + 13872

idk u tell me

step-by-step explanation:

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.
