1. Describe what a function does in your own words
A mathematical operation performed on an input variable that produces an 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

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

  1. Describe what a function does in your own words

A function is a formula where whenever you give an input there is a calculation done to that input that makrs a new output according to the calculation done.

  1. 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)

2.a) 4
b) 17
c) I dont know if zero is odd or even I would say ERROR?

  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.

Wow, this is a lot!

  1. A function is basically “I give you this, you do this, and then you get that.” For example, if the function is “add 3” then 1 would become 4.

I’m not that good at the ‘if’ or ‘is’ thing, but this is what I think is right…
a) 4
b) 17
c) 0

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

If you’re reading this and are doing the course, wish me luck and good luck to you too! :stuck_out_tongue_winking_eye:

  1. A function takes one piece of data (the input) and computes to give a new piece of data (the output).

  2. Where x is even: f(2)=4, f(4)=8, f(6)=12. Where x is odd: f(1)=11, F(3)=13, F(5)=15
    a) f(2)=2^2 = 4, f(2)=2+10=12
    b) f(7)=2^7=14, f(7)=7+10=17
    c) f(0)=0^2=0, f(0)=0+10=10

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

  1. A function is a type of computation which takes a variable, or input, and produces an output based on a formula that has been specified in the equation. (I remember loving formulas once I got a grasp on them in the past but I am going to need a brush up; any pointers are welcome now or in future instances.)

  2. f ( x ) = { x^2 if x is even; x+10 if x is odd }

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

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