Is the function #f(X) = 4X^2 + X^4 -120# even, odd or neither? Precalculus Functions Defined and Notation Symmetry 1 Answer Harish Chandra Rajpoot Jul 22, 2018 Even function Explanation: Given function: #f(x)=4x^2+x^4-120# #\implies f(-x)=4(-x)^2+(-x)^4-120# #=4x^2+x^4-120# #=f(x)# #\because f(-x)=f(x)# hence the given function is even function Answer link Related questions What functions have symmetric graphs?
