Step-by-step explanation:
The excluded values are any values of x that make the function undefined
Given
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
(x + 4)(x - 2)(x - 5) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
x = - 4, x = 2, x = 5 are the excluded values
Answer:
How does it need solved? By graphing? Substitution?
Step-by-step explanation:
The answer is 1/2 I think or 1
Answer:
To find the domains you must graph this equation and find the x-coordinates of the points plotted. That's the domain.
Remember, if two points have the same x-coordinate then do not repeat the number when stating the domain. Domain also always must be written in the least to greatest order. Domains must be written with {} enclosing them.
So if the x-coordinates were 4,5,6,4,7,5
You would write the domain as {4,5,6,7}
