When solving the equation, which is the best first step to begin to simplify the equation? -2(x+3) =-10
O (-2)(-2)(x+3)=-10(-2)
o
3(-2)(x+3) --10(-2)
o(x+3) - =10
03(x+3)--10
2

The pie is multyplued by the second step

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.
