The area of a triangle is 1/2 (x^2 - 2x +2x^2 -4). the height h is x+2 write an expression for the base b of the triangle. ( hint: area of a triangle + 1/2 bh)

21, i'm pretty sure it's right lol

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.
