I want to a dashed -- linestyle for the plotting of the d function. How would i be able to do that and add it to the code?
Code:
syms x
f = inline('x.^2*exp(-x)', 'x');
d = inline('x.^3', 'x')
ezplot(f, [0 10]); hold on
ezplot(d, [0 10])

Why are you using inline() ? inline() has been recommended against since MATLAB R13 (and I do not mean R2013a -- I mean before MATLAB starting numbering by year.)
Why are you using ezplot() instead of fplot() ? Are you using a version of MATLAB from before R2011b, before fplot() ??
You use syms but you do not do anything symbolic. inline() does not use symbolic variables.
You included MATLAB Compiler in your Products, but syms can never be compiled.

x = linspace(0,10) ;
y1 = x.^2.*exp(x) ;
y2 = x.^3 ;
plot(x,y1,'r',x,y2,'b')
Read about plot you can use your desired line style and marker.

Doing something like this would solve your dashed line problem:
syms x
f = inline('x.^2*exp(-x)', 'x');
d = inline('x.^3', 'x');
ezplot(f, [0, 10]); hold on
g=ezplot(d, [0, 10]);
set(g,'LineStyle', '--')
But, you might want to adjust the window, maybe add ymin, ymax.
