F(x) = 3 + Vx
What’s the domain and range

Domain: points where x can be defined.

As stated, the domain is -4 to 8.

The range is the y values where it can be.

So, the lowest y value to the highest y value.

f(-4) to f(8)

or

-12 to 24

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
