  1. a computation to verify the validity of the data.
  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)
  • b) f(7)
  • c) f(0)

Answer: it took me a long time to figure it out. lols. to make things easier
^ means x (multiply).

A. *x^2 if x is even

  • so if x is an even number, x multiply by 2

B. *x+10 if x is odd

  • so if x if odd, add x with 10

  1. f (2)
    (2)x2 =4 (use the A equation)

  2. f(7)
    (7) +10=14 (use the B equation)

  3. f (0)
    (0)x0=0 (use the A equation)

  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)-7

I see thanks alot I misunderstood the formula even and odd are the numbers given…so

1.F(2) will = 4 because 2 is a even number multiplied f(x)

  1. F(7) will = 17 because odd number f(7)+ 10=17

3 F(0) will = 0 because even function f(0) x 2= 0

F(x) = x/4-5

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

As per my understanding, to achieve some certain goals, we create a system where we write a set of mathematical instructions to achieve those goals in a specific manner called ‘syntax’ and this whole system is called function. Now, whenever desired or random ‘number’ or ‘information’ called input is processed through this function, then given input is manipulated according to the pre-written set of mathematical instructions in that function and produce a result called output.
