Jordan is kayaking upstream. The following equation models his speed: f(x) = 2x2 − 4x − 9, where x is Anna's speed relative to l
and. What is the domain of the function? x ≥ 1 x ≤ −4 x ≥ −9 All real numbers
1 answer:
Answer:
All real numbers
Step-by-step explanation:
The given equation is:
where x is Ana's speed.
This is a quadratic function.
A quadratic function is a polynomial function.
All polynomial functions are are continuous and defined for all real values of x.
Therefore the domain of
is all real numbers.

Yes it does you are correct!
Answer:
52 that is my anwer next question please
f(x) = sqrt [( x - 3) / (x - 5)]
well x cannot be 5 because that would make x - 5 = 0.
Also the fraction x - 3 / x - 5 cannot be negative because theres no real square root of a negative.
So x must be <= 3 or > 5
In interval notation the domain is ( -∞,3] or (5 , ∞)
