Find all roots in interval in equation

Please, help, need to find all rots from interval [-1;4] in equation:

sqrt(9)*sin(1.7*x)*log*(4.6-x)=0

Plot the relation. Surely you can do that? Does that tell you roughly where they are, and how many there are? Once you do that, why cannot you use a tool like fzero to find each root?

I'll even get you started.

fun = @(x) sqrt(9)*sin(1.7*x).*log(4.6 - x);
fplot(fun,[-1,4])
yline(0);

You need to make the effort though, as it is your homework assignment, not mine.

I don't have a big knowledges of Matlab, i try anyway, ofcourse, thanks for that anyway
