Determine the domain of the function

skelet666 [1.2K]

Answer:

Option B is correct.

The domain of the function h(x) is: $\{x | x\neq \pm 6 , x\neq 0\}$

Step-by-step explanation:

Domain states that the complete set of all the possible values of the independent variable where function is defined.

Given the function:

$h(x) = \frac{9x}{x(x^2-36)}$

To find the excluded value in the domain of the function.

equate the denominator to 0 and solve for x.

i.e

$x(x^2-36) = 0$

⇒x = 0 and $x^2-36 = 0$

⇒x = 0 and $x^2 = 36$

x = 0 and $x = \pm 6$

So, the domain of the function h(x) is the set of all real number except x = 0 and $x = \pm 6$

Therefore, the domain of the function h(x) is:

$\{x | x\neq \pm 6 , x\neq 0\}$

(x,5), (1,-5); slope- -5/2 . What is x?

Tom [10]

Answer:

-3

Step-by-step explanation:

The slope formula is y2-y1/x2-x1, so replace the variables with the given values.

-5-5/1-x= -5/2, now multiply both sides by "1-x"

-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides

-20/2+5/2=5/2x, now simplify the equation

-15/2=5/2x, multiply both sides by 2/5

-30/10=x or x is -3
