There were 4 people at the starting meeting. If those 4 people told 2 people about the march, and those 2 people told another 2, how would we write this function?

The function is f(x) = x + 2 when x > 4 and

                                  x       when x = 4

Step-by-step explanation:

Given - There were 4 people at the starting meeting. If those 4 people told

             2 people about the march, and those 2 people told another 2,

To find - How would we write this function?

Proof -

As given, initially , Total number of people = 4

After that, those 4 people told 2 people about the march

This means,

Total people know about the march = 4 + 2 = 6

Now,

Those 2 people told another 2

This means,

Total people know about the march = 6 + 2 = 8

∴ we get

The function is f(x) = x + 2 when x > 4 and

                                 x       when x = 4

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
