Hello, I am rewriting my answer because obviously there was an error.

Describe what a function does in your own words
Calculate the output of the following function

A function is used to calculate a result where the variable f (x) associates x with a number.

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

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) = f (x / 4) - 5

  1. Describe what a function does in your own words
    It calculates input and gives you an output to say it simply.

  2. Calculate the output of the following function
    a) f(x)=2^2= 4
    b) f(x)=7+10= 17
    c) f(x)=0^2= 0

  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.
    f(x)=x/4-5

  1. Describe what a function does in your own words

A function (computation) will give you an output after having provided an input.
f(x)=2x, if x=3, f(3)=2*3=6

  1. Calculate the output of the following function
f(x) = {

x^2 if x is even

x+10 if x is odd

}

• a) f(2)
• b) f(7)
• c) f(0)

f (2) = x^2 = 2^2 = 4
f (7) = x+10= 7+10 = 17
f (0) = x^2 = 0^2 = 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
