A jeweler states that she makes a 20% profit over her expensive for making gold necklaces. If she sells each necklace for $600 how much does it cost her to make each necklace

It is important because sometimes ur dna needs to multiply

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept

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.
