You have a branching function where you pick the output based on whether the number is even of odd. If X is even you square it, if its odd you add 10.

  1. Describe what a function does in your own words
    A function is a calculation that takes an input and changes it according to what is it told to change it by, then gives the result as an 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 (zero is an even 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.

f(x)= {(x/4)-5}

  1. Describe what a function does in your own words.

Answer: A function is a mathematical equation that computates an input number that calculates the output of another number.

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

x^2 if x is even

x+10 if x is odd

}

Answer: I don’t know. (Spoken in the voice of Jeff Spacoli)

what happened to the number 3 answer?:thinking:

#5125

I don’t know what this ^ symbol means. I attempted to google it and could not find a comprehensive explanation for it.

#5126

so 0 gets multiplied by 2, the answer is 0x2=0 :slight_smile:

#5127

multiplication of the number
