Describe what a function does in your own words:
A singular input/output calculation. -
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)=2^2
f(2)=4
* b) f(7)
f(7)=7+10
f(7)=17
* c) f(0)
f(0)=0^2
f(0)=0
3. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.

Describe what a function does in your own words
A function associates the relation of one set of numbers, to a second set, and exacts an amount. -
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)
**4**
b) f(7)
**17**
c) f(0) Two answers because function zero is both odd *and* even
**10 & 0**
- Write the definition of a function f that takes

A function does something to the input and gives us an output. What it does is defined by the function.
Example: f(x) = x+1 → f(7) = 8 -
- a) f(2) f(2)= x^2=4
- b) f(7) f(7)= x+10=17
- c) f(0) f(2)= 0^2=0
-
f(x)=(x/4)-5

1.A function is a block of code which only runs when it is called or a special relationship where each input has a single output.
-
Output
a) f(2) = 2^2 = 4
b) f(7) = 7 + 10 = 17
c) f(0) = 0^2 = 0 -

okay, that makes sense. zero is even because the number 10 is even, also zero is not null.

Function is a computation, that you give it an input, and through some mathematical calculation, it gives you an output.
“x” is variable. -
a) f(2) = 2^2 = 4 because 2 is even
b) f(7) = 7+10 = 17 because 7 is add
c) f(0) = 0^0 = 0 because 0 is even -
f(x) = (x/4) -5
