Yes I messed up with that, I thought the function was x^x for some reason and not x^2. I realised it after.
But thank you for the help :slight_smile:

  1. Describe what a function does in your own words - Function does simple calculations where you have an input and the result is the 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. f(x) = (x/4)-5

  1. Describe what a function does in your own words:

Function is computation that take an input and generate an output
a) f(2)= 2X2 = 4

b) f(7) = 7+10 = 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.

A function is a computation, a mathematical equation that has rules defined by the function.
f(x) = {x^2 if x is even f(x) = {x to the power of 2} if x = 2 the the answer = 4
f(x) = {x+10 if x is odd if f = 3 then 3 = 10 = 13
a) 4
b) 7
c) 0
