Domain restrictions are values of x which are not acceptable in a function.

They may be arbitrary because we simply want to ignore them. eg y = x^2 between 0 and 4

They may make no sense in the context, eg graph a compounding investment over next 20 years.
Negative values for x make sense here.

They may avoid mathematical impossibilities eg y = (x^2 - 4x) / (x - 4) which must avoid dividing by zero, so x cannot = 4.
The graph will look like the line y = x but have a hole where x= 4

Answer:

The correct option is A) The growth factor of the investment.

Step-by-step explanation:

Consider the provided exponential function.

$V(t) = 30,000(1.125)^t$

Where V(t) is the total value after t years.

Here the function is in the form of Exponential Growth:

$y = a(b)^x$

Where b value is the growth factor.

By comparing we get that the constant '1.125' represents the growth factor by which our value is increasing each year.

Constant '30,000' represents the initial value i.e. the investment made.

Hence, the correct option is A) The growth factor of the investment.

Ganezh [65]

Answer:

x = 4

Step-by-step explanation:

<u>Step 1: Set both parts equal to 0</u>

x - 4 = 0 and x - 4 = 0

<u>Step 2: Solve for x by adding 4 to both sides</u>

x - 4 + 4 = 0 + 4 and x - 4 + 4 = 0 + 4

x = 4 and x = 4

Answer: x = 4
