Does somebody know how to plot this function?

I have the exercise to plot this function:

I have to use an anonymous function

That's my code until now:

figure; hold on;

y = @(x) tan(3*x) + 5*x-4;

x = linspace(0,180);

plot(x, y(x) ,'c');

axis([0 180 -100 1000]);

title('Funktion y = tan(3x)+5x-4');

xlabel('x-Werte[°]');

ylabel('Funktionswerte');

But I don't know how to get the parts between the tangent 
or if my solution is even the right beginning, can somebody help?

Use tand rather than tan, because the argument 3*x is in degrees rather than radians.

Increase the number of points to see the asymptotes better. Here I've used 1000 points total.

figure; hold on;

y = @(x) tand(3*x) + 5*x-4;

x = linspace(0,180,1000);

plot(x, y(x) ,'c');

axis([0 180 -100 1000]);
