  1. Function is computation (input =-output)

2.a) f(2)= 2X2 = 4

b) f(7) = 7+10 = 17

c) f(0)= 0

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

  1. Describe what a function does in your own words

A function creates a mathematic script to automatically produce an output when the variable is added.

  1. Calculate the output of the following function
    • a) f(2) = 4

• b) f(7) = 17

• c) 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.
F(x) = (x/4)-5

Good job! You have it perfectly right :ok_hand:

The parity of zero is even.

#618

The parity of zero is even.
So 0^0=0 (defined)
Undefined is the lack of having a value.

Yeah :grin: and the parity of zero is even, so it’s just zero.

#620

2 is even, so f(2)=2^2=4

#621

1- A function is a mathematical artifact that generates an output for a given input.

2-

  • f(2) = 4 2 is even
  • f(7) = 17 7 is odd
  • f(0) = 0 0 is even

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

  1. Describe what a function does in your own words
    Takes a number and calculates it in the give function to obtain result
    i.e. f(5)= 4x -1 then f(5) = 19

  2. Calculate the output of the following function
    (a) f(2) = 4 if x is even
    (b) f(7)= 17 if x is odd
    © f(0)= 10 if x is odd

  3. f(x)/4 = x-5
    Iff x=2 then
