If #g(x) = 5 - sqrt(x+30)#, how do you solve g(-34)?
Unvalid expression in real number set,
There's nothing to "solve" actually, you simply need to evaluate the function in the point. This means to substitute every "
Doing so we get
Now, if you're working with real numbers, you can't calculate the square root of a negative number. This means that
If you're working with complex number, then
