Question 1039929
<pre><b>
Did you mean {{{y=f(x) = 3sqrt(x) - 2}}} or this {{{y=f(x) = 3sqrt(x - 2)}}}?

If you mean the first, then type

f(x) = 3sqrt(x) - 2

If you mean the second, then type

f(x) = 3sqrt(x-2)

That's why parentheses were invented, so people
could explain what they mean by grouping words
or mathematical expressions together. Without
parentheses, algebra would be chaotic.  

Also to show exponents you must use this symbol ^ 
between the base and the exponent. x3 just means
3x, but x^3 means x<sup>3</sup>.

By the way, none of those choices could possibly
be the inverse function of a function involving
the square root function.  It would have to be
of degree 2, but all the choices you gave are
either of degree 3 or 1.  So I think you copied
the choices from the wrong problem.
