  1. a function is an instruction to carry out a specific action withint a mathmatical equation
  2. Calculate the output of the following function
  • a)
    2 = even
    f(x) = x^2 if even
    f(2) = 2^2
    f(2) = 4

b) 7 = odd
f(x) = x+10 if odd
f(7) = 7 + 10
f(7) = 17

c) 0 is even
f(0) = (0^2)
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.

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

Functions HW

  1. Describe what a function does in your own words

A) A Function is a mathematical formula that you can create that will take in data and give you a result

  • 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. Functions accept an input (number), process it in a set manner and provide an output (number)
    eg. If a function doubles whichever input number it recieves, an input of 4 outputs 8, input 10 outputs 20

  2. a) 4
    b) 17
    c) 0
