What is the domain of the function f(x) = sqrt1/3x+2

Mathematics
1 answer:
Nookie1986 [14]3 years ago
7 0

Answer:

x ≥ -6

Step-by-step explanation:

Please use parentheses around the argument (input) of the sqrt function:

Better:  sqrt( 1/3x + 2)

Much better:  sqrt ( (1/3)x + 2)

The input to the sqrt function must be 0 or greater.  Thus, we must solve the equation (1/3)x + 2 ≥ 0.  Mult. all 3 terms by 3, we get x + 6 ≥ 0, or x ≥ -6.

The density of Venus, compared to Earth having a density of 1,
guapka [62]

Answer:

Mercury

Step-by-step explanation:

We'll translate this into ratios.

First, V:E = 0.943:1

Then, M:E = 0.983:1

We already have their density in terms earth's density. They are in the same unit. So, we can compare them directly, with greater ratio means greater density. It's clear that Mercury has the greater density.
