Answer:
Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
Answer:
Q(-10) = 299
Step-by-step explanation:


(-10 to the second power is 100 (negative times a negative equals a positive)
3 times 100 equal 300

Divide both sides by -3, and replace
with
. Then

Factorize the quadratic in
to get

which in turn means

But
for all real
, so we can ignore the first solution. This leaves us with

If we allow for any complex solution, then we can continue with the solution we ignored:

0.08 divided by 1.44 is 0.055555556
