h(x)=ax^{3}+(2a-1)x^{2}+bx

depends on the real constants

a

and

b

. a. (i) Find all values of

a

and

b

for which

h(x)

is an odd function. b. (ii) Find all values of

a

and

b

for which

h(x)

is an even function. c. (iii) For

a=2

and

b=-3

, classify

h(x)

as even, odd, or neither, giving a clear reason for your answer.
