Please help!! Use the graph to determine the amplitude, period, and phase shift of the function.

A. ) amplitude: 3; period: 2; phase shift:0

B.) amplitude: 4; period: 1; phase shift:1

C.) amplitude: 3; period: 1; phase shift:0

D.) amplitude: 4; period: 2; phase shift:2

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.
