Only if it's a function.
no, because xx=x squared, and x squared is not linear
If you mean: y = 2x+5 then yes it is a linear function of straight line
The result depends on how the function f() is defined. Simply copy the function definition, replacing every "x" (assuming the function is defined in terms of "x") by "x+5".
The function f(x) = 3x + 2 can take any real value, so the question does not seem to make any sense.

No, f(x) = x + x^5 in not linear.
No, it is not.
It is x - y + 2 = 0

Look for points where the denominator is equal to zero. In other words, solve the equation: denominator = 0

No.
