Answer:
The function is even because f(x) = f(−x).
Step-by-step explanation:
we know that
An even function is one for which
f
(−x)=f(x) for all x in its domain.
An odd function is one for which
f(
−x)
=−f(x) for all x in its domain
In this problem we have

so

therefore
f
(x)=f(-x) for all x in its domain.
Is a even function

Answer: QE = 10
Step-by-step explanation: To solve this problem, it's important to understand that the diagonals of a parallelogram bisect each other.
This means that E is the midpoint of diagonal SQ.
So we can setup the equation x² + 9x = 4x + 6.
To solve this polynomial equation, set it equal to zero first.
So we have x² + 5x - 6 = 0 and we get (x + 6)(x - 1) = 0
when we factor the left side of the equation.
So this means that x = -6 or x = 1.
However, -6 will give us a negative length when we plug it in
to find QE so this will not work.
However, plugging 1 in will give us 10 as a length so QE = 10.
