Remember that you cannot take the log of a negative number, regardless of the base. Also, you can take the logarithm of zero, since no number raised to a power can equal zero (although it come very close).

Therefore, (x+3), the number inside the logarithm, must be greater than zero.

x+3 > 0
x > -3
The domain is x > -3,
or (-3, ∞) in interval notation

Answer:

17. 5

18. 17

Step-by-step explanation:

The distance formula is used for the purpose.

d = √((x2 -x1)² +(y2 -y1)²)

17. d = √((3-6)² +(1-5)²) = √((-3)² +(-4)²) = √(9+16) = √25 = 5

The distance between the points is 5 units.

18. d = √((-1-7)² +(12-(-3))²) = √(64 +225) = √289 = 17

The distance between the points is 17 units.
