Question 32937
f(x)=3x^+2x-4
equate f(x)=0 to get the roots
now
3x^+2x-4=0
this is a quadratic in x
*[invoke solve_quadratic_equation 3, 2, -4]
<P>
So you have your 2 values of x
<P>
If you were looking for the domain and range for the function f(x),please post again,clearly stating the question
Hope this helps,
