your graph is moved up vertically 3 units and its amplitude is cut in half as compared to the parent function
Explanation:
Use this standard formula to convert from the parent function
a = amplitude
b = horizontal stretch
c = horizontal shift
d = vertical shift
your function has a amplitude of
graph{cosx [-10, 10, -5, 5]}
So your graph is moved up vertically 3 units and its amplitude is cut in half:
graph{1/2cosx + 3 [-10, 10, -5, 5]}
