Its a mathematical rule that calculates an input giving the calculated output

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

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

  1. A function is a computation that determines an output from a set of given inputs.

  2. I’ve never seen the ^ symbol in an equation. Admittedly I needed to look for the explanation. “And” meaning multiply is a new one.
    a) 4
    b) 17
    c) 0

  3. f (x) = ( x / 4) - 5
    Can anyone clarify if the brackets would actually be needed in this instance as division and multiplication are usually prioritised in an equation, right?

  1. Describe what a function does in your own words - it makes a computation/calculation based on an input and, as a result, it delivers 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. - f(x) = x/4-5

1: A function is a set computation that takes an input value, then manipulates that value and outputs an output value.

2:
a = 4
b = 17
c = 0

3:
f(x){
y = x / 4
y - 5
}

Hey @JasaInc, hope you are great.

I think you forgot to type the “x” variable in your equation, maybe you want to redesign the answer :nerd_face:

If you have any more questions, please let us know so we can help you! :slight_smile:

  1. function is an equation where you have x as the variable in the equation.
    2)a- F(2)= 2(2)=4
    b-F(10)=7+10
    c- F(0)=2(0)=0
  2. F(x) =(x/4-5)
