The period of the tangent function is PI. The period of y= tan(2x) is PI over the coefficient of x = PI/2
tan(2x) = 2tanx/(1 - tan2x) So tan(2x) +1 = 2tanx/(1 - tan2x) + 1 = 2tanx/(1 - tan2x) + (1 - tan2x)/(1 - tan2x) = (-tan2x + 2tanx + 1)/(1 - tan2x)
The range of y=2x is All Real Numbers
y=|x|/4 The range is [0 , ∞ )
The range depends on the domain, which is not specified.

The range of y=2x is All Real Numbers
If you mean y =9x^2 -4 , than the range is the possible y values. Range = 0<= y < infinity.
y=|x|/4 The range is [0 , ∞ )
The range depends on the domain, which is not specified.
The range depends on the domain.
The function y=x is a straight line. The range is all real numbers.
y ∈ ℜ
y < 1
The domain is the x values, so x = 0 to 10. The range is the y values, so y = 0 to 25.
The single value -7.
