What is the domain of f(x)=3x/x-1?

2 answers:

6 0

Answer is C.) all real numbers except 1

3 0

For this case, we have by definition the domain of a function is given by all the values for which the function is defined.

We have the function:

$f (x) = \frac {3x} {x-1}$

It is not defined when the denominator is 0. This is when:

$x-1 = 0\\x = 0 + 1\\x = 1$

Thus, the domain of the function is given by all the real numbers minus the 1.

Step-by-step explanation:

*Note:

The distance formula is derived from the Pythagorean Theorem.

Step 1: Define

Identify

Point (5, 10)

Point (10, 12)

Step 2: Find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(10 - 5)^2 + (12 -10)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{5^2 + 2^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{25 + 4}$
[√Radical] Add: $\displaystyle d = \sqrt{29}$
