  1. A function is the directive given to a variable (input) that will ultimately result in an output

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

f(x)= (x/4)-5 (honestly im guessing this is whats meant by write the definition. I hope.

  1. Describe what a function does in your own words

Function calculates the output from the input according to the parameters given to it.

  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.

A function is a computation. It is an input that adds an output.

  • a) f(2)=4
  • b) f(7)=17
  • c) f(0)=0

F(x)=(x/4)-5

This was very hard for me to understand. Took a while to grasp. I have a lot of math practice to do till I feel comfortable. Practice I shall.
