This is a problem involving the subtraction of two functions f(x) and g(x):
<span>if f(x)=3x-1 and g(x)=x+2, find (f-g)(x). In other words, find:
</span><span> f(x) = 3x-1
-{g(x) -(x+2)
-----------------
f(x) - g(x) = 3x - 1 - x - 2 = 2x - 3 (answer)</span>
Answer:
y = -3/2x - 3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope Formula: 
Step 1: Find slope <em>m</em>

y = -3/2x + b
Step 2: Find y-intercept <em>b</em>
3 = -3/2(-4) + b
3 = 6 + b
b = -3
Step 3: Rewrite linear equation
y = -3/2x - 3
In the situation, the number of bacterias are doubling for each sheet of paper cut, thus, the exponential equation for the puber is:

Initially, there was only one sheet of paper. Then, each sheet is cut in half, so we will have 2 sheets, then 4 sheets, then 8 sheets, and so on. That is, the number of sheets is continuously doubling, thus, the population after n cuts can be modeled by the following <u>exponential equation</u>:
