Please help! To determine the interval in which a function is increasing. Graph the function using a graphin calculator OR your

knolwedge of parent functions and thier transformations OR create a table of values (aka T-Chart) to help you determine what points to plot on your graph.
Once you have a graph of your function, you can then look to find the portion of your graph where it is increasing (moving upwards to the right).


For the function below, we see that the function is increasing on the interval [0,∞)

This means that when you look at the graph you will see it begin to increase when x=0 and all values towards the right.

On a number line we would show the interval where the function is increasing indicated with the red arrow pointing to the right of 0 since our function is increasing from 0 to infinity.
At what interval is the function is decreasing. (ie moving downwards from the upper left side) ?
A(-3,0]
B(-∞ ,0]
C(-4,0)
D(-1.5, 1.5)

A colony of 50 bacteria double in size every 30 minutes. What will the population be 120 mintues from now?
valkas [14]

Answer:

800 bacteria

Step-by-step explanation:

Over here, we have exponential growth.

So we have 50 bacteria

Every 30 minutes, it doubles in size

In 120 minutes, there are four 30 minutes.

So you do 50 * 2 * 2 * 2 * 2

Do that out and you get 800

Let me know if you have any questions

240 is 60% of what number?
Brums [2.3K]
Hi there! To find the answer to that question, we can write and solve a proportion. Set it up like this: 240/x = 60/100. This is because we're looking for the whole and we already know the part, which is 240. Cross multiply the values in order to get 24,000 = 60x. Now, divide each side by 60 to isolate the variable. When you do, you get x = 400. You can check this by dividing and then multiplying that quotient by 100. 240/400 is 0.6 and 0.6 * 100 is 60. That makes 60%. There. 240 is 60% of 400.

   ln 5
e              =    ?
                                    x
Keep in mind that y=e     and y = ln x are inverse functions of one another.
  ln 5
e       ,  we can drop both the "e" and the "ln 5."  We are left with 5 (answer).
                                                                                        ln 5
Alternatively, we could take the ln of both sides of y = e

which will result in ln y = (ln 5) ln e.  Note that ln e = 1 (these two functions are inverses of one another).

Then we are left with ln y = ln 5.  Dropping the "ln" operator from both sides,

y=5 (same as before).
