I could bark out the boilerplate response for low-effort copypasted homework questions, but I'm out of breath today. Let's settle for a compromise. Here's a conceptual example that is intentionally not exactly what you need, but can be rearranged with some minor effort.
f = @(x) (x.^2 + 2*x +2) ./ (exp(x) + x.^(1/2) .* cos(x)); % define function
out = f(1:15) % evaluate the function at some integer values
out = 1×15
1.5344 1.4705 0.9254 0.4879 0.2482 0.1232 0.0592 0.0275 0.0125 0.0055 0.0024 0.0010 0.0004 0.0002 0.0001
This example defines an anonymous function, which should be sufficient for the task, but there are other ways to define a function. Refer to the docs:
