  1. A function returns a computation based on input.

  2. Given f(x)
    a) f(2) = 4
    b) f(7) = 17
    c) f(0) = 0

  3. A function f that takes an input x, divides it by four and then outputs that result subtracted by 5 would be
    f(x) = (x/4)-5

Use the X^2 function if the input requested to be used is even.

Use the X+10 function if the input requested to be used is odd

X^2 means that you square the input (multiply it by itself) which (in this instance the variable is an even number which A) f(2) is)

f(2) is even so the function is 2 squared which equals 4
2x2 = 4

The second variable requested to be used is f(7)
This is an odd number
Hence the second formula is used
7+10 = 17

The third variable is 0
This is an even number
Hence the first formula is used
0x0 = 0

Does that make sense to you?

  1. A Function is a formula. It defines the operations to occur using mathematical syntax with whatever variables are provided. The variables are the inputs and are substituted into the syntax to compute an output. In essence a function is the logic portion of a math problem.

  2. a. f(2)
    In this instance the input is even
    Use the even formula for the computation
    2x2
    2x2 = 4

  3. b. f(7)
    In this instance the input is odd
    Use the odd formula for the computation
    7+10
    7+10 = 17

  4. c f(0)
    In this instance the input is even
    Use the even formula for the computation
    0x0
    0x0 = 0

  5. f = x/4-5
