Find an equation for a sinusoidal function that has period π, amplitude 1, and contains the point (π/4,1) Write your answer in the form f(x) = Acos(Bx + C)+ D, where A, B, C, and D are real numbers.​

1. 3/6 or 1/22. 1/123. 1/84. 1/105. 2/12 or 1/6

It doesn’t show the question

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.
