Write the expression -3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2 in simplest form. then, answer the following questions using complete sentences. how many terms are in the simplified expression? how many of the terms in the simplified expression are negative?

2x^2-y^2+5xy-2y there are four terms in the simplified expression. There are two negative terms in the simplified expression.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
