Question

WILL MARK BRAINLIEST!!!
Determine if the following function is even, odd, or neither.

f(x) = -9x4 + 5x + 3

A.Odd
B.Even
C.Neither

Answer 1

$f(x) = -9x^4 + 5x + 3\\\\ f(-x)= -9(-x)^4 + 5\cdot(-x) + 3=-9x^4-5x+3\\\\ f(-x)\not =f(x)\implies \text{ not even}\\\\ -f(x)=-( -9x^4 + 5x + 3)= 9x^4 - 5x - 3\\\\ -f(x)\not =f(-x) \implies \text{ not odd}$

Neither
