    6x + 1

    Step-by-step explanation:

    f (x) = 2x; g (x) = 3x + 1

    Wee need to find f0g

    f0g = f (g (x)) = f (3x+1)

    substituting the value in x of f (x)

    f (3x+1) = 2 (3x+1) = 6x + 1

    f (g (x)) = 9x² + 6x + 1

    Step-by-step explanation:

    f (x) = x², g (x) = 3x + 1

    f (g (x)) = f (3x + 1) = (3x + 1) ² = 9x² + 3x + 3x + 1 = 9x² + 6x + 1
