  1. Describe what a function does in your own words
    A function is a set of instructions which you can activate by giving it some variables. It will give you results back whic[/quote]h you can process further.

f(x) = {

x^2 if x is even


x+10 if x is odd

I’m embarrassed to say I just can’t get my head round the calculations. Can anyone share a link to some learning resources ideally for children? I don’t want to proceed until what I see makes sense.

One needs to learn algebra basics to understand it better way. There are many YouTube videos out there.

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

Function is computation which is follow certain mathematical rules.

a) f(2)= 2X2 = 4

b) f(7) = 7+10 = 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.

  1. A function takes input values and performs a defined mathematical task on them to produce an output value.

a) 4
b) 17
c) 0

  1. f(x) = {(x/4) - 5}
    While I appreciate that using bodmas the brackets don’t need to be added to x/4 I’ve added them for readability

  1. Describe what a function does in your own words
    A function is an algorithim that will play a preset role and bring a result every time it’s put to work.

  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) = 2 + 10 = 12**
*** b) f(7) = 7^2 = 49**
*** c) f(0) = 1**

  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.

FUNCTIONS:

  1. A ‘function’ is a computation. We use the function sign here to start the computation with its inputs and outputs.

You haven’t defined what ^ is. You should not assume everyone knows what that symbol means. A Google search shows that this is not obvious. https://www.rapidtables.com/math/symbols/Basic_Math_Symbols.html

For this purpose I will assume as others have that it means ^ = X

(a) 4
(b) 17
© 0

a = even x 2 b=odd + 7 c = zero

  1. Again to me it is not clear what you are asking here when you say definition because I would say 'what is the formula for… going by other people answers. I understand what has been taught just not how it is phrased!

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

  1. Describe what a function does in your own words

A function is a math formula where you can alter an input with a variable to get an output.

  1. Calculate the output of the following function

a) x = 4
b) x = 17
c) x = 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
