Here's my code:
function myf(x)
for x= [-10 -7 0 2.4 5 6 10]
f= (5.*x.^3 + 15.*x.^2 + x + 10).*sin(x)
y=f^-1
x1= x - f/y
end
z=plot(x1,f)
end

If you want to plot the function over a region , then you can try something like this.
x = linspace(-10, 10, 1001);
y = myf(x);
plot(x, y), grid on, xlabel('x'), ylabel('f(x)')
% Setup your math function
function y = myf(x)
y = (5*x.^3 + 15*x.^2 + x + 10).*sin(x);
end

Thought your original problem is about making the graph "appears".
Can you lookup the MATLAB code for Newton's Method (on Google) and post it here?
It makes troubleshooting your problem easy for you and me.
Just make sure you edit the Newton's code to fit your mathematical problem.
