Answer:

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
