Issues with entering into MATLAB

hello all I am trying to enter this into MATLAB but cant seem to get it right

x = 0:0.1:10
y= (2*x^1.01)+ sin(3*pi/2 *x)-10*cos(x)-3 

plot(x,y)

[x,y]=ginput(n) % find the first 2 zeros 

Please let me know if I am right or i did it wrong.

Thank you

This sems to be homework.

Vectorise the expoinentiation:

y= (2*x.^1.01)+ sin(3*pi/2 *x)-10*cos(x)-3; 
       ↑ ← HERE 

Then to find the approximate indices of the zero-crossings:

zxi = find(diff(sign(y)));

Then use those with interp1 to find much more precise estimates of the zero-crossing x-values.
