y=x+1
5tanx=1 turns into tanx=1/5 then you use a calculator use the calculator function tan^(-1) this function should be the 2nd function of tan then in the parenthesis that come up type in 1/5 you should get .1974 therefore tanx=1/5 => x=.1974
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
If your calculator has an exponentiation function, simply raise the number to the power of .5 Remember this trick: the nth root of X = X ^ (1/n)
No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
y=x+1
a four function calculator = x - + / if you have google you have this :)
Yes.

Using the Sine function Sin(x) = 0.5 Then x = Sin^(-1)0.5 x = 30 degrees. Sin^(-1) in the inverse function on you calculator. . It works for Sin , Cosine and Tangent of any angle.

No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
f(f(x)) = f(x). Only if f is 1-1 then we have a solution f(x)=x.
