Consider the function f(x) = g(x) + h(x)
Where
What is the period of the function f(x) ?
10

Let f(x) = x2, g(x) = tan(x) and h(x) = ln(x). What is [fo(fof)](2) equal to ?
2
8
16
256
D.
256
We have f(x) = x2 And we have to calculate the value of [fo(fof)](2) that means f(f(f(2))).
Now, f(f(x)) = (x2)2 = x4
Then, f(f(f(x)) = (x2)4 = x8
f(f(f(x))) = 28 = 256
hence, option D is correct.
Let f(x) = x2, g(x) = tan(x) and h(x) = ln(x). For x = , What isvalue of [ho(gof)](x) equal to ?

If, x = logc (ab), y = loga(bc), z = logb(ca), then which of the following is correct ?
xyz = 1
x + y + z = 1
(1 + x)-1 + (1 + y)-1 + (1 + z)-1 = 1
(1 + x)-2 + (1 + y)-2 + (1 + z)-2 = 1
