Como puedo allar la amplitud, el periodo, el cambio de fase y la ecuación​

If i’m not wrong i believe it is c

A=bxh3.2x1.8=5.76 centimeters square

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
