First differences are 2, 4, 8, 16, which is a geometric sequence. The parent function is not linear (constant first difference) or quadratic (first difference increases by the same amount from one to the next). When the first differences are a geometric sequence, the underlying sequence is a geometric (exponential) sequence.

1st blank: exponential

Translation up adds a constant to each of the f(x) values.

2nd blank: f(x)
3rd blank: increased by 5<span>

For the last blank, you're looking for an (x, f(x)) pair that is translated to (x, f(x)+5).

4th blank: </span><span>(2, 16)</span>

In this experiment, the scientist cools the gases. This means that she decreases the temperature of the gases.
Based on this, the changes in the temperature will be negative for this experiment to indicate that the gases are losing energy (heat energy).

What is a simpler form of the expression?<br> (4k + 5)(3k^2 - 4k - 4)
Maru [420]

Answer:

12k^3 -k^2-36k-20

Step-by-step explanation:

<u>Step 1:  Distribute</u>

(4k + 5)(3k^2 - 4k - 4)

(4k * 3k^2)+(4k*-4k)+(4k*-4)+(5*3k^2)+(5*-4k)+(5*-4)

12k^3-16k^2-16k+15k^2-20k-20

<u>Step 2:  Combine like terms</u>

12k^3+(-16k^2+15k^2)+(-16k-20k)-20

12k^3 -k^2-36k-20

Answer: 12k^3 -k^2-36k-20
