Determine which function has the greatest rate of change as x approaches infinity.
a). f(x) = 2x − 8
b). g(x) = 5x2 − x + 7
c). h(x) = 4x − 6
d). there is not enough information to determine the answer.

How to determine whether two known pairs of points are on the same line.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

Icould really use some with this question.
