a. 4
b. 17
c. 0
f(x)= (x/4)-5 :slight_smile:

#6281

  1. Describe what a function does in your own words - A function is a relation between san input or set of inputs and respective outputs. example - f(x) = x^2 it means whatever input we give for x, the output would be 2*2

  2. f(x) = {
    x^2 if x is even
    x+10 if x is odd
    }

  • f(2) = 4
    -f(7) = 17
    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
#6282

Result:
It is a mathematical term that describes parameters (rules) that enables to get an output that relates to the given input.
a) f(2)= 2X2 = 4
b) f(7) = 7+10 = 17
c) f(0)= 0"
f (x) = (x/4)-5

#6283

  1. A function is the execution of a predefined mathematical calculation

  2. a) 4 b) 17 c) 0

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

#6284
  1. Describe what a function does in your own words
    computation that takes an input, transforms it and gives an output. Same input: same 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
#6285
  1. A function is a computation where it has an input and in return you receive an output.
  2. a=4 b=17 c = 0
  3. f(x) = x/ 4 = - 5

  1. Describe what a function does in your own words:

A function takes an input and uses a formula to mathematically compute a resulting output.

  1. 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

#6287

  1. Functions are computation outputs based on inputs.

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

#6288

a) 4
b) 17
c)0

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

#6290

  1. A funtion is like an equation

  2. 4
    17
    0

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

#6291

  1. Describe what a function does in your own words
    A function is a set of instructions, you give it a input it does the action you told it to do and give you a output

  2. Calculate the output of the following function

What will be the output for the following inputs?

  • a) 4
  • b) 17
  • c) 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
#6292

  1. Describe what a function does in your own words
    A function is a calculation or equation that outputs different results based on the value of the input.

  2. 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)
There is no calculation since zero is neither positive nor negative.

  1. Write the definition of a function f that takes an input x, divides it by four, and outputs that result subtracted by 5.
    f(x) = (x/4) -5
#6293

  1. a function is a mathematical equation that receives an input, performs the prescribed equation using the input, and provides an output.

  2. 4, 17, 0

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