HURRY!!

Write a function rule for the table.
F(x) = x - 4
F(x) = x + 4
F(x) = 4 - x
F(x) = -4x

Answer :

The function is
F(x)=x-4

Explanation:

Given values in table :

x f(x)

3 -1

4 0

5 1

6 2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4
