Graph Method Root Finding

'X - 2^(-X) = 0'

how can I find the roots of this equation by using graphic method? fplot()

[darova]

What about plot?

[James Tursa]

E.g.,

x = -1:0.01:1; % pick some x range to look for a root
plot(x,x-2.^(-x)) % plot the equation
grid on

or

fplot(@(x)x-2.^(-x));
grid on

Then zoom in on the 0 crossing.
