uhh.. You probably already have enough schoolwork to do, but could you help me understand what a function is by telling me whether this is true or not?

The definition of Function from Merriam-webster:
A mathematical correspondence that assigns exactly one element of one set, to each element of the same or another set. A variable (As a quality, trait, or measurement) that depends on and varies with another [24].

A function has three main parts: 50 x 2 = 100

1. The Input
2. The Relationship
3. The Output

What goes into the function is put inside a Parentheses after the function name.

For example: The value of f (x), for (x = 2), is f (2)

The (x) is a place-holder that shows you where the input goes and what happens to it.

This function: f (x) = x² takes the Input (x = 2) and squares it.

So the (x²) takes the Input of (2) and gives the Output of 4

This can also be written as f (2) = 4


Other symbols besides (x) can also used.

The function: f (x = 2) = 1 - (x) + (x²) = 3

f (x = 2) = 1 - (x) = ^-1

^-1 + (x²) = 3

The same function, but with (θ) for the Input's place-holder: f (θ = 2) = 1 - (θ) + (θ²) = 3

f (θ = 2) = 1 - (θ) = ^-1

^-1 + (θ²) = 3

Whatever the symbol may be, the result will be the same [00].

The purpose of a function is to relate an input, to an output.

h(Gear) Gear x 20Km/h
h(2) = 40Km/h

The function takes the input (Gear of the car), and relates it to an output (The Speed, multiplied by 2).

Yo! it's Marti!! lol I haven't talked to you in a while how are you??

Thank you for the fav!

Thanks so much for the fav!! I'm liking your work. Keep it up!!
