Write the range of the function f(x) = e^{x – [x]}, X ∈R.

0 ≤x-[x]<1

e⁰ ≤ e^x-[x] <e¹

1 ≤ e^x-[x] < e

Therefore, R(f) = [1, e)

If f(x) = cos2[π²]x + cos [-π²] x, where [x] denotes the greatest integer less than or equal to x, then write the value of f(π).

Write the range of the function f (x) = cos [x], where

LetThen write the value of α satisfying f(x)) = x for all
x ≠ - 1.

If then write the value of

Write the range of the function f(x) = ex – [x], X ∈R.
