G4. determine which of the following functions are even, which are odd, and which are neither. (a) f(x) = x 3 + 3x (b) f(x) = 4 sin 2x (c) f(x) = x 2 + |x| (d) f(x) = e x (e) f(x) = 1 x (f) f(x) = 1 2 (e x + e −x ) (g) f(x) = x cos x (h) f(x) = 1 2 (e x − e −x ).

Given below

Step-by-step explanation:

A function is said to be odd if

(a)

odd function

(b)

odd function

(c)

even function

(d)

neither odd nor even

(e)

odd

(f)

even function

(g)

odd function

(h)

odd function

no

step-by-step explanation:

2-7=-5
