In the attached diagram you can see the graph of the function 
As you can see graph is:
1. increasing from x = −2 to x = −1
2. decreasing from x = 0 to x = 1
3. decreasing and then increasing from x=1 to x=2
4. increasing from x=2 to x=4.

Answer:
71°
Step-by-step explanation:
95° + 14° = 109°

By substitution
f(6) = 1.8×2^(6)
= 1.8×64
= 115.2
