plot a function that will go from [0,0] to [5,8], from there it will go to [10,0] and then to [13,-4] using sine, cosine, logarithmic, quadratic and exponentional functions] in matlab

main.m
% defining the functions
x1 = linspace(0,5,50);
y1 = sin(x1);

x2 = linspace(5,10,50);
y2 = log(x2-4)+2;

x3 = linspace(10,13,50);
y3 = -2*(x3-10).^2+8;

% plotting the function
