Reflection of a function

reflection of f(x) about x-axis
So
(3×1/2) + (6×3/4) + (3×1) + 1 1/4 +1 1/2=11.75

Answer:
See explanation
Step-by-step explanation:
Consider triangles CAX and BAX. In these triangles,
- given
- given
- reflexive property
By SAS postulate, 
Congruent triangles have conruent corresponding parts. So,

Consider triangles CXY and BXY. In these triangles,
