#### Answer:

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]}
