A function is a computation that allows to insert an input and gives an output.
-
a) 4
b) 17
c) 0 -
f(x) = (x/4)-5
-
A function is a computation whereby an input is given certain directions within the function to come out with an output.
2). a) 4
b) 17
c). 0 -
f(x)= x/4 - 5
Thanks Fabrice for explanation. Now I know what that ^ means. At school we never used that star gate symbol. It was always like this - 3².
-
A function is a computation that takes in an input with specific rules and returns an output.
-
a). f = 2^2 = 4
b). f = 7+10 = 17
c). f = 0^2 = 0 -
f(x) = (x/4) - 5
Question a. is correct but it’s not an addition. It’s an exponent.
- Describe what a function does in your own words
- the value of x is squared if x is even, and is added to 10 if odd.
- 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
- Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.
myFunc(x) = {
var newVal;
newVal = (x/4) - 5;
return newVal;
}
*quick update after remembering to use the code format button - * - Thanks @thecil. =)

Homework on Functions - Questions
- Describe what a function does in your own words
- A function is a computation. It computes your input and gives you an proper mathematical output.
- 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
- 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
Thank you I will correct it , I am coming back to Math after many many years
-
A function is a subroutine that recieves information as an input, applies a process to that input and returns an out put based on the results.
-
a) f(2)=4
b) f(7)=17
c) f(0)=0 (honestly it depends on how the language you are programming in handles 0, another likely outcome is an error) -
f(x) = (x/4) -5
-
Describe what a function does in your own words.
A function is a computation that has an input and an output. -
Calculate the output of the following function.
a. f(2)
f(2) = 2 x 2 = 4
b. f(7)
f(7) = 7 + 10 = 17
c. 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.
Answer: f(x)=/4-5
1 - A function is a piece of code or a set of instructions that receives an input, does something with it and gets an output.
2.a) f(2) = 4
2.b) f(7) = 17
2.c) f(0) = 0
3 - f(x) = (x/4) - 5
You’re lucky that 2+2 = 2^2
Check this post for the meaning of ^
Yes, in written language we use it like this. In computer science, we use that symbol ^ for power relations.
0^2 will never have errors. (defined) It’s perfectly fine. However, dividing by zero is another issue.
You forgot an ‘x’, you can’t start with a division without a numerator.
f(x) = x/4 - 5
1- A function is a variable “instruction” that is applied to the input.
2- a) 4
b) 17
c) 0
3- f(x)=(x/4)-5
- A function takes an input, which can be anything, and turns it into an output by running it through an equation.
2a. 4
2b. 17
2c. 0 - f(x)= (x/4)-5
1.)A function is a math equation , by having a variable with an input that computes an output. In this case “X” being the variable.
2.)
a.) 4
b.) 17
c.)0
3.) f(x)= (x/4)-5
- A function f(x) is a mathematical concept. We talk about it when we have an input and output.
2 f(x)=4
f(x)=odd
f(1)=11
