The function f(x) = 2x^3 + 3x^2 is:
(a) even
(b) odd
(c) neither
(d) even and odd

d). Even and odd

Explanation:
2x^3 = even
Since any number times 2 will be even
3x^2 = even/odd

Let’s assume x = 2
Then 3(2)^2 = 3 x 4 = 12 = even

Assume x = 3

3(3)^2 = 3 x 9 = 27 = odd

Now we know our equation has:

even + even/odd = even and odd

Ex: 2 + 2 = 4 = even
Ex: 2 + 3 = 5 = odd
So our equation can be equal to either even and odd

B.the point lies directly on the regression
