Which item is true of f(x) and g(x)? They are inverses if f(g(x)) = g(f(x)) = -x

They are inverses if f(g(x)) = g(f(x)) = 1

They are inverses if f(g(x)) = g(f(x)) = x

They are inverses if f(g(x)) = g(f(x)) = 0

I think the answer should be there in versus if f g of x is equal to G F of x = 2 x

sine

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
