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

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
