  1. Describe what a function does in your own words
    You define a computation to be applied on the input and the function use this computation to get you 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)=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

  1. A function is a equation that is attributed to a name. If i decide that the letter f is equal to x+2, the output gonna be my number +2. soo if x=1 , f(x)= 1+2=3

2.a. 2x2=4
b. 7+10=17
c. 0x2=0

  1. A function is a computation with set parameters that gives an output based on the input of variables. For example, if there was a function defined as f(x) = x+3, whatever variable that would be input as x would always result in an output that is the variable defined(input) +3, eg x=4, output would be 7.

  2. f(x)= x^2 for even numbers, and f(x) = x+10 for odd numbers

A. f(2)= 4. As x(2) is an even number in this function, the parameters tell us the output must be defined as 2^2 which equals 4.
B. f(7)= 17. As x(7) is an odd number in this function, the parameters tell us the output must be defined as 7+10 which equals 17.
C. f(0)=0. As x(0) is defined mathematically an even number, the function tells us that the output of the function must be determined as 0^2 which equals 0.

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