  1. A function is a list of instructions to perform a mathematical statement
  2. f(x) = { x^2 if x is even

x+10 if x is odd}

A f = 2^2 if x is even (2 x 2 =4) Answer is 4
B 7+10 if x is odd (7 +10 = 17) Answer is 17
C 0^2 if x is even (2 x 0= 0) Answer is 0

Every sentence you typed made prefect sense to me, before that I was completely lost which means I am far behind on understanding the rules of algebra. I am going to check the links out on top and get up to speed with any information I find. So if there are no parenthesis separating the odd and even statements in between the{} does this make it a “or” statement? I cannot figure out why “or” is used and sometimes not use in programing or in this specific statement.

    • Describe what a function does in your own words?

A function is a relation that maps a set of inputs, or the domain, to the set of outputs, or the range. Note that for a function, one input cannot map to more than one output, but one output may be mapped to more than one input.

  • 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) => f(2)=2^2=4

  • b) f(7) => f(7)=7+10=17

  • c) f(0) => f(0)=0 or f(0)=10

    • 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

0 is considered an even number so only one is correct :wink:

  1. Function could be described as a mathematical equation, in which the input values based on a defined function would vary the output values.

  2. a)4
    b)17
    c)0

x^2 if x is even

x+10 if x is odd

}
```
What will be the output for the following inputs?

  • a) f(2) —> 2*2 = 4
  • b) f(7) —> 7+10= 17
  • c) f(0) —> Error or 0

3. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.

why Error? Zero is an even number, So F(0) = 0^2 = 0.
