Question

2x^4-x^2+9 odd or even?

Answer 1

Answer:

Since x4−2x2=x4−2x2 x 4 - 2 x 2 = x 4 - 2 x 2 , the function is even. Since the function is not odd, it is not symmetric about the origin. Since the function is even, it is symmetric about the y-axis.

Step-by-step explanation:

Answer 2

Answer:

2x^4 - x^2+9

This equation is unfactorable but the roots are:

x=√1+i√712, −√1+i√712, √1−i√712, −√1−i√712

And the x and y intercepts are:

x-intercept(s):None

y-intercept(s):(0,9)
