Hellos Im new in matlab and I have no idea how to graphic
I want to graphic the ecuation
eqn = (-3+3*x)/x <= 0
sol = solve(eqn,x,'returnconditions',true)
fplot(sol,[-5 5])
I doesn't understand how use this command
And Im not very good in English
Thaks, Have a nice day

eqn = @(x) (-3+3*x)./x <= 0
eqn = function_handle with value:
@(x)(-3+3*x)./x<=0
fplot(eqn,[-5 5])

The given inequality does not have explicit solution. Therefore, by ignoring analytical constraints, these can be obtained:
syms x
% Define EQN:
EQN = (3*x-3)/x <= 0;
% Solve:
SOL = solve(EQN, x, 'returnconditions', true, 'IgnoreAnalyticConstraints', true);
% Solution and Conditions
Solution = SOL.x
Solution = 
x
Conditions = SOL.conditions
Conditions = 
% Plot the inequality solution
fplot(Solution, [-5, 5], 'DisplayName', '(3*x-3)/x <= 0')
