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)

Answer:
17i
Step-by-step explanation:
d= (under radical sign) (x2-x1)^2 + (y2-y1)^2
plug in the numbers and simplify and youll get (again under the radical sign) (-8)^2 + (-15)^2
do the math again and youll get -289 under the radical. square root of 289 is 17 and you add the i next to it because it is negative and those numbers aren't real
