What value of u makes the equation true. ?

u - 9 = -7u + 7

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

The graph is supposed to show f(x) = 3 sin (x/4+1) - 1/2. which of the following are correctly represented in the graph? select two of the following that apply.
