How do i use fzero to solve the following

My code reads as follows:
time2 = [0:1:4000];
y = log10(62) - log10(49) - 0.000084*time2;
fzero(y,1200)
I need to use fzero to calculate the value of time2 when the above equasion is zero. I don't know why it wont work as above but despite my best efforts nothing will stick.
Cheers
p.s. i need to use fzero so alternative solutions, whilst welcome, won't solve my problem.

That is not how to use fzero. As its help clearly states and shows, the first argument must be a function handle, which you have not provided. Try this:
>> fun = @(t) log10(62) - log10(49) - 0.00008*t;
>> fzero(fun,1200)
ans = 1277.4
and reading the MATLAB documentation.
