How can I plot two functions in the same graph?

I have a code like this:
fplot(@(x) cosh(x))
hold on
p(x) = 0.6671x^3-1.7921x^2+2.7580x-0.089
fplot(@(x) p(x))
hold off
since p(x) is a more complex function. And when I try to run the code, the command shows "Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters,
or other syntax error. To construct matrices, use brackets instead of parentheses."
I don't know how to fix for this. Please me, thank you!

fplot(@cosh)
hold on
p = @(x)0.6671*x.^3-1.7921*x.^2+2.7580*x-0.089;
fplot(p)
hold off

Try this:
fplot(@(x) cosh(x));
hold on
fplot(@(x) 0.6671x^3-1.7921x^2+2.7580x-0.089);
