Question 1118872
g(x) is how?
{{{sqrt(x)-1}}} or {{{sqrt(x-1)}}} ?



<i>LATER</i>:  You wanted  {{{g(x)=highlight_green(sqrt(x-1))}}}.


I will do only one of the four examples.
{{{f*g=f(x)*g(x)}}}
{{{(1-3x^2)sqrt(x-1)}}}
and you might leave the function in this form, or 'simplify' to {{{sqrt(x-1)-3x^2*sqrt(x-1)}}}.


DOMAIN:  Obviously if real numbers,  the factor needs to be such that  {{{x-1}}} is NOT negative; so {{{x>=1}}} is the domain.
