Question

Which notation shows that P is the function of x?

Answer 1

Option a
P(x)
shows that P is the function of x

Answer 2

Answer A

Think of a "function" as modifying our variable (x).

we place our variable "into" the function to change it.

this can help you remember the notation because we place our variable (x) "into" the parentheses, just like we place the variable "into" the function

I hope this help!:)
