Determine algebraically whether the given function is even, odd, or neither. g(x) = 8x³ + 4.

the sides of a square all have a side length of y.  Write a simplified function in terms of y for a rectangle whose length is twice the side length of the square and whose width is 2 units longer than the side length of the square. A(y)=

Evaluate this function at x=−5. Write the exact answer. Do not round. If the answer is undefined, write Und as your answer. F(-5)=
