How do you find the intersection points of two functions?

i have A=10+0.5*n;

P=8*exp(1.02*n) where n=1:110

i want to find the point when P>A ,numerically and graphically

It is straightforward to show that P>A for the entirety of ‘n’.

They do not ever intersect:

n=1:110;
A=10+0.5*n;
P=8*exp(1.02*n);

Out = P(P>A);                           % Desired Result

figure
plot(n, A,    n, P)
grid
ylim([min(A)  max(A)])

They would intersect at 0 if ‘n’ was allowed to have any negative values, and was continuoous.
