  1. Describe what a function does in your own words
    It’s a piece of functionality that can be called later, a bit like a black box that has input then it performs some function (does some processing) then returns an output

  2. Calculate the output of the following function

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

I was stuck with this one too… it’s a multiplier, so 5^2 like 5 to the power of 2

  1. A function is one or more rules that are applied to an input and yield an output

  • a) f(2)=2x2=4
  • b) f(7)=7+10=17
  • c) f(0)=0x0=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. A function is basically a computation that has an input and then receives an output.

2a. Since x is the input value, the output will be 4.
b. Since 7 is the input value and is an odd number, the output value will be 17.
c. Since 0 is the input value, the output value will be 0.

  1. f(x) = {x /4 - 5}
    F is the function. X is the input value which divides 4 and then subtracts 5.

1. Describe what a function does in your own words
- A function takes input values and performs a defined mathematical task on them to produce an output value.

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
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.
c) f(0) = {(x/4) -5}

  1. Describe what a function does in your own words. A function is a computation. It takes some kind of input, applies a calculation of some kind, and returns an output.

  2. f(x) = {
    x^2 if x is even
    x+10 if x is odd

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

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

1- Function is a means to define a specific computation.

2 a- 4
b- 17
c- 0

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