Find the domain for the rational function f of x equals quantity x end quantity divided by quantity x minus 5 end quantity.

Gennadij [26K]

Answer:

All real numbers except for 5.

Step-by-step explanation:

$f(x)=\frac{x}{x-5}$

The domain of rational functions is determined by the denominator. The denominator cannot equal zero since if they do, the function will be undefined.

Thus, we need to find the zero(s) of the denominator to determine the domain.

$x-5=0$

$x=5$

Therefore, the domain of the rational function is all real numbers except for 5.

In set builder notation, this is:

$\{x|x\in \mathbb{R}, x\neq 5\}$

Answer:

50mph

Step-by-step explanation:

Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.

A = 50+10

b = 50-10

A = 60

B = 40

A2 = 120

B3 = 120

120 = 120
