A function is odd if:
f ( - x ) = - f ( x )
A ) f ( - x )= 0.8 ( - x ) ^3 = - 0.8 x^3 = - f ( x )
Answer: A ) f ( x ) = 0.8 x^3 is an odd function.
Functions B ) and C ) are even and D) is neither even nor odd.
Answer:
f = - 1
Step-by-step explanation:
f - 6 = f + 8
f - 6 = - (f + 8)
f ∈ ∅
f - 6 = - (f + 8)
