A wave is modeled with the function y(x, t)=0. 25\cos(0. 30x-0. 90t \frac{\pi}{3})y(x, t)=0. 25cos(0. 30x−0. 90t 3 π ) where all lengths are in meters and all times in seconds.

did you get the answer yet?

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
