  1. Describe what a function does in your own words.

A function takes an input and calculates an output based on the function’s formula.

  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) = 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.

f(x)=x/4-5

a function manages a mathematical process or formula for a given input to determine the output for that input following criteria or guidelines determined by the details of the function structure.

a. 4
b. 17
c. 0

3 f(x) = x/4 - 5

  1. If a function is given a number - input, it calculates an output

a) f(2) f(2x2) = 4
b) f(7) f(10+7) = 17
c) f(0) f(0) = 0

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

I think it is a typo error, f(x) = (x/4) - 5

#5356

That is how I’m used to writing ‘divide’ :slight_smile:
but I guess it should be in brackets (x:4)-5

Wow I am Math Challenged so thanks for the links to the math symbols. Now that I know the “carot” is an exponant it makes this a lot easier.

  1. A function is a math equasion where you put in a veriable input and get out an output according to the peramiters you set up. (I think, please correct me if this is wrong)

a. 2 squared (2x2) = 4 (because its even)
b. 7+10 = 17 (because its odd)
c. 0 squared (0x2) = 0 (because its even)

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