2 was to solve this:

1. Definition of an Inverse Function.

A inverse function states that if we have a function f(x), by definition of a function,, we have ox and y values that map with each other. In an Inverse function, the x and y values will swap places so that y map to x.

$f {}^{ - 1} (0)$

implies that what value of x will give us 0. here it is 6.

The other way is to find the equation of f(x). We have a y intercept of 3, a negative slope. And the value of the slope is 1/2 so the equation in slope y intercept form.

y=-1/2x+3.

Then we apply rules for solving for inverse of functions.

Swap x and y

x=-1/2y+3

Solve for y

x-3=-1/2y

-2x+6=y

Now plug 0 in for x

0+6=6

so 6 is the value of inverse function.

Hello, please consider the following.

We know the following, right ?

$(\forall a, b \in \mathbb{R}) \left( sin(a+b)=sin(a)sin(b)+cos(a)cos(b) \right)$

So, here, it gives.

$Asin(\omega t+\phi)=Asin(\phi){\sf \bf sin(\omega t)}+Acos(\phi){\sf \bf cos(\omega t)}\\\\=c_2{\sf \bf sin(\omega t)}+c_1{\sf \bf cos(\omega t)}\\\\\text{ *** where }c_2=Asin(\phi) \text{ and } c_1=Acos(\phi) \text{ ***}$

Do not hesitate if you need further explanation.

A customer calls and has questions about the bill for their first month's subscription. They want to know why the monthly rate i

Sunny_sXe [5.5K]

The most likely thing that has happened in this case is that a fee is paid for the registration.
The function that best models this problem is:
y = 45x + 15
Where,
x: number of months.
Y: payment of each month.
For the first month we have:
y = 45 (1) +15
y = 45 + 15
y = 60
answer:
the most likely reason for the bill being this amount is
registration fee.
