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
