Solve the differential equation by variation of parameters.
y'' + y = sin x

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Which will form a composite function?

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas
