For what values of k will the function f(x)=3x^2+4x+k=0 have no zeros, one zero, 2 zeros

Math( help please ! ) 
Reiny,
you will have to look at the discriminant b^2  4ac
b^24ac = 16  4(3)(k) = 16  12k
If 1612k = 0 you have one zero
if 16  12k > 0 you have 2 zeros
if 1612k < 0 you have no zeros
solve each case to find the corresponding value of k
