  1. Describe what a function does in your own words

A function gives us rules in which to operate by. Anything that we input into the function must follow its rules, the result is called our ‘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. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.
    answer: f(x) = x/4-5

Homework on Functions - Questions

  1. Describe what a function does in your own words
    A function is an input generates an output. The output is related to the input.

  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. 4 ; f(2) = 2^2
B. 17 ; (7) = 7+10
C. 0 ; (f0) = 0 +,-,*,/ or ^ 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
    Example, x=100
    f(x) = (100 / 4) - 5
    f(x) = (25) - 5
    f(x) = 20

Q1, Describe what a function does in your own words

A, - a function is a mathematical equation in which X is a variable

  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) …….Answer is, 4

b) f(7) …….Answer is, 17

c) f(0) …….Answer is, 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

Answer is, f(x)=x/4-5 or (x/4) - 5, although both will render the same result.

Result……My brain is now like mashed potato!

A function is an input computation that gives an output.

A. 2 to the power of 2 is 2 x 2 = 4
B 7 is odd number so 7 + 10 = 17
C 0 is even number so = 0

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

That was so hard, took me hours to work out, I can’t remember algebra :see_no_evil: looks like I ll have to start practising!
