Is y=x^4+3x^2 even, odd, or neither?
erma4kov [3.2K]

Answer:

<h3>               EVEN</h3>

Step-by-step explanation:

the product of odd numbers is always odd

the product of even numbers is always even  

the product of odd number and even one is always even

the <u>sum of two odd </u>numbers is always <u>even</u>

and the sum of two even numbers is always even

so if x is even number we have:

x²=x•x   - even number

x⁴=x²•x²  - even number

3x²=3•x²  - even number

y = x⁴+3x²   <u>- even number</u>

and if x is odd number we have:

x²=x•x   - odd number

x⁴=x²•x²  - odd number

3x²=3•x²  - odd number

y = x⁴+3x²   <u>- even number</u>
