Choices for edgunity test:

A: 10

B: 12

C: 14

D: 16

B is the correct answer!

Answer 2

Answer: The value of g(4) =12

Explanation:

From the given function, only
`g(x)=0.5x+10\ \ \ 4\leqx\leq8` has the domain which contains x=4.

[Since 4 does not lies in
`0\leq x\leq 4` and
`x\geq8` ]

Therefore, to calculate the value of g(4) we put x=4 in the above function we get

`g(4)=0.5(4)+10\\\\\Rightarrow\ g(4)=2+10\\\\\Rightarrow\ g(4)=12`

Therefore, the value of g(4) =12
