A function is a calculation based on a given equation and an unknown set to see where in the function (or the graf if you printing out the function) you wanna look.

A) f(2)=2^2-> f(2)=4
B) f(7)=7+10->f(7)=17
C) f(0)=0

  1. f(x)=x/4-5

  1. Describe what a function does in your own words
    Every unique input creates an unique output
  2. 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) = 0
  1. 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

a) only equals even x 2 when x = 2
a number raised to the second power would be that number times itself once
f(4) = 4^2 = 4 x 4 = 16

b) should be odd + 10

cool?

A function runs some computational or mathematical operations on given input value(s) to produce output value(s).

f(x) = x^2 if x is even
f(x) = x+10 if x is odd

f(1) = 1+10=11
f(2) = 2^2 = 4
f(7) = 7+10=17
f(0) = 0^2 = 0

f(x) = (x/4) - 5

1 a function just describes an input and its output, a calculation

2
a x = 4
b x = 17
c x = 0 is not defined in the function above

3 f (x) = (x/4) - 5

If you had told me in gymnasium that I was ever going to use this in future, I would have declared you crazy!

function is a computation
a) f(2) = { x^2 if x is even x+10 if x is odd} 2^2 is 4 (even)
b) f(7) = { x^2 if x is even x+10 if x is odd} 7^2 is 14 (even) 7+10 is 17 (odd)
c) f(0) = { x^2 if x is even x+10 if x is odd} 0^2 is 0 (even) 0 + 10 is 10 (even)

f(x/4) = x - 5 if x = 20 than f(20/4) = 5 - 5 is 0
