1. Describe what a function does in your own words
A function is the computation process of taking the input, performing an action to it like addition, subtraction, multiplying and dividing, and the finished equation is the output.

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 ^ 2 = 4

b) f(7) 7 + 10 = 17

c) f(0) 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. A function is the infrastructure for a mathematical equation, where “x” is the variable
    Replacing the variable with a known produces an output based on the infrastructure of the equation, so,

2.a) f(2)= [x (squared)] 2X2 = 4
2.b) f(7+10) = 17
2.c) f(0) = 0

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

so, you get a function With a variable ‘x’

f(x) = {

x^2 if x is even

x+10 if x is odd
}

so the first question (a) asks for the output if that variable ‘x’ = 2.
so change x to the number 2 and check.
so 2 = even. So then you do 2^2 (wich is 4)
if x is an odd number you need to do +10
