plot(t,f(t),'co-','linewidth',2,'markeredgecolor','c','markerfacecolor','c')
hold on

Please try changing the values on the y-axis: add this code to your code
%get insight on the maximum and minimum values of your two functions
g_val=g(t);
f_val=f(t);
ax=axis; % show axis range for your first plot
%let the y-axis values be from the min to the max of your functions above
axis([ax(1:2) min(f_val) max(g_val)])

thank you for your answer but this is not exactly what i wanted but actually i need it and i will use it on another plot on x axis.
now this image will explain what i want, acctually i want less than that like [0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 .....4] and it doesn't have to be 0.00002 just 0.2

I suppose the follwoing should help. However, it does not display upto 4; but shows what you want
set(gca,'yticklabel',[0:0.2:4]);

You should keep in mind that it's only the labeling that has changed; but the axis limits remain the same as for the data. View this with the following:
ax=axis;

x = 1:7;
y = x./7;
plot(x, y, 'o-');
yticks(y)

You can use the TickLabelFormat property of the axis ruler object stored in the YAxis property of the axes.
figure
h = plot(x, y, 'o-');
ax = ancestor(h, 'axes'); % Get the handle of the axes in which the line was plotted
yticks(y)
ax.YAxis.TickLabelFormat = '%0.8f'; % Change the format of the tick labels on the y axis
