Homework on Functions - Questions

  1. Describe what a function does in your own words

Functins are computations . They are like a set of rules or laws about what happens with different inputs based on circumstanses and what will be the output

  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) = 2^2 = 4

  • b) f(7) = 7+10=17

  • c) f(0) = 0 ^ 2=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

  1. Describe what a function does in your own words
    A function is an object sequence based on a pattern. Where the object is a number and the pattern is a formula equation. Giving that function a number returns the result of that equation. Important to note that if we treat numbers as objects then objects can have properties or conditions eg odd or even numbers etc

  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) f(2) = 2^2 = 4
b) f(7) = 7+10 = 17
c} f(0) = 0 or false

  1. Describe what a function does in your own words
    A function is a computation that gives an equal unit to calculate an output.

  2. Calculate the output of the following function
    f(x)=2

x^2 if x is even. I am lost on this question as I have no understanding of the equation.
Not familiar with this symbol ^ ???
Need help understanding the formula before I can have a go at answering the question.

x+10 if x is odd. Again I didn’t understand the equation to give an answer.

What will be the output for the following inputs?
a) f(2)=2
b) f(7)=14???
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.

1. Describe what a function does in your own words

A function is a process that takes an Input (usually a number) and after some processing and calculations it returns an Output.
A function always does the same processing in every Input.

2. 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)
2 is even, we calculate according to the first branch of the function
f(2) = 2^2 =4

b) f(7)
7 is odd, we calculate according to the second branch
f(7) = 7+10 = 17

c) f(0)
0 is even, we calculate according to the first branch
f(0) = 0 ^ 2 = 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

The ^ is an exponent, its often used in text editors that don’t support the numbers above the base number.

7 is an odd number, so you must add 10.

What do you need help with? You must construct a function (f(x)) based on the instructions. :slight_smile:
