How can I plot the graph?

I want to plot the function where y=x/3 until y=25 where it is constant y=25
function output = carFunc(x)
if (x >= 75)
output = 25;
else
output = x/3;
end
plot(x,carFunc(x))
end

x = 0:100;
plot(x,carFunc(x));
ylim([0 30])
function output = carFunc(x)
output = zeros(size(x));
idx = (x >= 75);
output(idx) = 25;
idx = (x < 75);
output(idx) = x(idx)/3;
end

What does output=zeros(size(x)); do?
"output=zeros(size(x));" allocates memory for the variable output and initializes it with 0s. This may make the code more efficient.

function output = carFunc(x)
x=0:0.1:75;
if (x >= 75)
output = 25;
else
output = x/3;
end
plot(x,output)
end
