    g (x) = 5x + 2.

    r (x) = x

    b (x) = 1/2 x³

    k (x) = - 3 x + 1

    Step-by-step explanation:

    The function notation ⇒ it is the form to write the function, It is meant to be a precise way of giving information about the function, like f (x), v (x) and so on.

    Given the following:

    g (x) = 5x + 2.

    y = 1 x

    h = x²

    r (x) = x

    f/x = x⁵ - 3

    b (x) = 1/2 x³

    p/x = - 7x

    k (x) = - 3 x + 1

    y = mx + b

    fx = - x³ + 4

    So, in the given options the following are in function notations:

    g (x) = 5x + 2.

    r (x) = x

    b (x) = 1/2 x³

    k (x) = - 3 x + 1
