Find an equation for the graph shown to the right Type the equation in the form y = A sin (ox) or y = A cos(x). y= (Type an exact answer, using as needed. Use integers or fractions for any numbers in the expression.) TN

Answer 1

Amplitude - 3 45 ET point. from masumum the starts Here the graph so we can take cos function. the cos tunchiun equation We have y = A corres a – – (1) = 20 where Here period, T = 49 - me - 22 Amplitude - 3 Refledled y Her the have cosine to fit graph is negatur refroled. That means Sin in the equation We

If the graph is not reflected A not reflecler it looks like this. The sign the is negative is because graph reflected
