Creating a piecewise function using for and if

For an assignment, I need to create a piecewise graph using only for and if statements, but I have two equations, 15 + 2*(x-1), x>=2, and 15 if x is between 0 and 2 for a data set of 0:0.1:5 I am not sure how I would construct this.

% Here are some hints for your try

% data set of 0:0.1:5
x = 0:0.1:5;

% for loops over x
for i=1:length(x)
    % if statements
    if x(i) satisfies certain conditions
        do whatso ever
    else
        do something else
    end
end
