  1. A function is a mathematical equation that takes a syntax, or an input, and gives us an output.

  2. f(2) = { 2^2 = 4}
    f(7) = { 7 + 10 = 17}
    f(0) = {0^2 = 0}

  3. f(x) = {( x/4) - 5}

  1. Describe what a function does in your own words
  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)
  • b) f(7)
  • c) f(0)

A little help here please. I’m getting

a) f(4)
b) f(9) <— if ^2 is a caret and is essentially and, why is everyone else getting 17?
c) f(0)

#5953

I am not sure, how you get 9.

f(x) = {

x^2 if x is even

x+10 if x is odd

}

Is a branching function. Simply meaning you decide the path the function will take based on the function input. So in case where x = 7, it means that x is an odd number and therefore you use the second path (x + 10) = 7+ 10 = 17.

#5954

Ahh, I see what I did wrong. Thanks :slight_smile:

  1. You give something to a function which is input and and then you get output.

a) f(2) 4
b) f(7) 17
c) f(0) 0

  1. f(x)=4-5
