  1. Describe what a function does in your own words

A function executes a line or lines of code that are contained in it when called.

  1. 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 something that will take an input, and based on the assigned input, it will produce an output.

A. F(2) = 2(2)=4
B. F(7) = 2(7)=14
C. F(0) = 2(0)=0

  1. F(x) = [(x/4)-5]

  1. Describe what a function does in your own words

A funtion is a math equation where an input in changed by a variable to get an output.

  1. Calculate the output of the following function

What will be the output for the following inputs?

Im not gonna pretend I was smart enough to come up with the answers on my own. Reading other people answers I now understanding how the functions work. multiply the number by 2 if x is an even number and add 10 if x is an odd number.

  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.

Copied and pasted this. I always hated math in school and was never very good at it. Reading the answer i can understand how people got there but i couldnt get there on my own.
f(x) = x/4 - 5
