  1. Describe what a function does in your own words
    A function is a mathematical calculation that changes the output depending on what input is entered

  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 computations write has F in syntax way , it does created a input based by a number given and result a output number. F (x) = X= + 1 = output.

2/ A 4
B 17
C 0

3/ f(x) = (x/4)-5

  1. Describe what a function does in your own words
    A function is a mathematical mechanism that takes in input, does something with the input, and gives back 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
  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.

0^2 = 0 (and it’s definitely defined) only dividing by zero is problematic.

#697

When x is even do x^2
When x is odd do x+10

Replace x with 2. This is even, so f(2)=2^2=4
Replace x with 7. This is odd, so f(7)=7+10=17
Replace x with 0. This is even, so f(0)=0^2=0

f(x) = {
x^2 if x is even - then the Output will will be even results.
x+10 if x is odd - will be always odd.
}
