So the variable is x and the curve is a sine curve. But it is squashed along the horizontal or x axis by the constant 2 since it crosses zero and reaches max and min twice as often . So what are the x values for these points? Also it is stretched vertically or along the y axis by the constant -3. The negative sign tells you that the sine curve is flipped over about the x axis. Finally the 5 tells you that it is shifted vertically up by 5 so the resulting wiggle is along the line y = 5, rather than the line y = 0 or the x axis. Thanks from Kirtana Devaraj
