What is the domain of x^3 -2 +1
1 answer:
Answer:
All real numbers
Step-by-step explanation:
Assuming the polynomial is
Then the domain is all real numbers.
The domain are all values of x, for which the given function is defined.
The reason is that, polynomials are defined everywhere on the real number line.
We can write this as {x|x is all real numbers} .
Or (-∞,+∞)

Answer:
Step-by-step explanation:
The domain of a function is all of the values that can be under that specific function. In this case, we're asking what values of
allow
to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to , because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for
:
Solving this inequality, we get:
(Subtract
from both sides of the inequality to isolate
)
(Multiply both sides of the inequality by
to get rid of
's coefficient)
