Answer:
The function has a domain of all real numbers.
The function has a range of {y|–∞ < y <∞ }.
The function is a reflection of y=∛x
Step-by-step explanation:
Given:
f(x)=-∛x
domain is set of all values that x can take for which the function is defined, so
for above function domain= set of all real numbers
range is set of values that corresponds to the set of values of domain, so for given f(x) range={y|–∞ < y <∞ } set of real numbers
Now f(x)=-∛x hence its reflection will be
-f(x)=-(-∛x)
y=∛x !
Answer:
Step-by-step explanation:
A circle is described by an equation in the following form:
(1)
where:
is the x-coordinate of the centre of the circle
is the y-coordinate of the centre of the circle
r is the radius of the circle
For the circle in this problem, we have:
- The centre is located at (2,-8), so
- The radius is 11, so
Therefore substituting into eq(1) we find the equation of this circle:
So the correct option is option B:
The slope is the number besides x which in this case is 14 while your t intercept is 9
