A function performs mathematical calculations on what is put into it.

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

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

  1. A function allows a computation to input rules (what x is equal to) and leads to the output. And as others have mentioned (cheating here) allows variables to have a say in the output.

  2. I got confused due to the writing of this I guess but trying to crack it actually helped in the end and made it easier :slight_smile:
    a)where f(2) would be f(x) = 2^2 = 4
    b) where f(7) where x is an odd number which is seven so, using the calculation above:
    f(7) = (7+10) = 17
    c) f(0) where f(x) = (0^2) = 0

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

  1. Describe what a function does in your own words
    Function is structured out of 2 components, input and output. It takes the input and makes calculations as instructed within the function, and finally gives us the output.
  2. Calculate the output
    f(x) = {
    x^2 if x is even
    x+10 if x is odd
    }
    f(2) = 4
    f(7) = 17
    f(0) = 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.
    f(x) = (x/4) – 5

A function is made of input and output. Output delivers the value out of input with the formula inserted into the function.

x^2 if x is even
x+10 if x is odd
}

  • b) f(7)=17
  • c) f(0)=0

  1. A Function is a Calculation. You are taking a formula with a variable. The Function will solve for that variable based on the input given to it.

a) f(2) = (2)^2
= 4

b) f(7) = (7)+10
= 17

c) f(0) = 0

  1. f(x) = x/4-5
