15. Dorothy is looking for the solution set to the equation 5 sın +35x+5. She graphs the equations y= -2x +35x+5 and y = 5sin x-7 and she says that the solution is X- -0.132. Is she correct? Yes; the solution is the point of intersection of two trigonometric equations. No; the solution of a trigonometric equation should never be negative. No; to solve a trigonometric equation, she should isolatexand substitute. No; this trigonometric equation has two solutions. y=5sin(-n)어 4 (-0.132, 0.331) -6 -4 -2 2 4 y = -2x2 + 35x + 5 2. 15.
