Every day, there are 2 times more likes on the internet video of a bird which is modeled by the function c(n) = (2)^n-1, where n

is the number of days since the video posted. On the first day, there were 122 likes. What is the function that shows the number of likes each day?

Answer:
C(n) = 122 * 2^n

Explanation:
We are given that:
Each day, the number of likes increases two times compared to the previous day. This means that we can write the function as follows:
C(n) = 2*C(n-1)

We are given that:
C(0) = 122 likes (initial value)
Therefore, our function would become:
C(n) = 122 * 2^n

Now, let's test this function:
C(0) = 122 * 2^0= 122
C(1) = 122 * 2^1 = 244 (this is twice c(0))
C(2) = 122 * 2^2 = 488 (this is twice c(1))
.....and so on

Hope this helps :)

Write the equation of a line that contains (2,−2) and perpendicular to another line with slope −1.
Reika [66]

Answer:

y = x - 4

Step-by-step explanation:

Perpendicular slope = 1

y + 2 = 1 (x - 2)

y + 2 = x - 2

y = x - 4

Describe a scenario where the function value exists at x=c, but the limit does not exist.
Vikki [24]

The scenario can be described using a piecewise function like:

f(x) = 1/x                  if  x < c.

f(x) = x                    if   x = c

f(x) = 1/(x + 73)       if x > c.

<h3>When the value exists but the limit does not?</h3>

Remember that the limit only exists if the limit from left and the limit from the right give the same value.

Then, we can just define a piecewise function of the form:

f(x) = 1/x                  if  x < c.

f(x) = x                    if   x = c

f(x) = 1/(x + 73)       if x > c.

Clearly, this is not a continuous function.

Notice that:

f(c) = c.\\\\ \lim_{x \to c^{-}} f(x) = 1/c\\\\ \lim_{x \to c^{+}} f(x) = 1/(c + 73)

So the limits from left and right are different, then:

\lim_{x \to c^{}} f(x)

Does not exist.
