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.

Answer:

Option C

A DVD has a diameter of 26 centimeters. What is the area of the DVD? Round your answer to the nearest hundredth. Use 3.14 for π.
Alinara [238K]

Answer:

A =530.66 cm^2

Step-by-step explanation:

A DVD is a circle so we can use the formula for area of a circle

A = pi r^2

We can find the radius from

r = d/2  where d is the diameter

r = 26/2

r = 13

A = pi *13^2

A = pi *169

Substituting in for pi

A = (3.14) * 169

A =530.66
