Functions do mathematical calculations on input value and give us output value.
a) f(2) = 2^2 = 4
b) f(7) = 7+10 = 17
c) f(0) = 0^2 = 0
- f(x) = (x/4)-5

- A function describes an action to be performed with an input. Generally this is written in a mathematical formula.
-
a. 2 = even, so formula f(x) = x^2 applies. F(2) = 2^2 = 4 b. 7 = uneven, formula f(x) = x+10 applies. F(7) = 7+10 = 17 c. 0 = even, so formula f(x) = x^2 applies. F(0) = 0^2 = 0 - F(x)=(x/4)-5

Describe what a function does in your own words
a function apply a mathematical rule to any given input producing an output result. -
Calculate the output of the following function
f(x) = {
x^2 if x is even
x+10 if x is odd
}
What will be the output for the following inputs?
- a) f(2) f(2) = {4}
- b) f(7) f(7) = {17}
- c) f(0) f(0) = {0}
- Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.
f(x) = (x/4) -5

zero is technically even, so zero times zero equals zero

A function is a mathematical computation where an input creates an output with predefined characteristics (eg f[x] = x + 1) -
Calculate the output of the following function
f(x) = {
x^2 if x is even
x+10 if x is odd
}
What will be the output for the following inputs?
- a) f(2) = 2^2 output = 4
- b) f(7) = 7+10 output = 17
- c) f(0) = 0^2 output = 0

Describe what a function is in your own words:
A function is instructions that you can input in order to get a specific output. It’s a computation that follows mathematical rules. You input a certain value to get a certain output value (Oh God I struggle with defining this lol) -

f(x)=(x/4)-5
I see some people have put the parenthesis and some have not. If someone can explain to me which is correct I would be ever so grateful 
Thank you!

it’s not a big deal, because multiplication and divisions have priority to adding or subtracting.
