Find the domain of the function (f/g)(x), given f(x) = x² - 4x - 21 and g(x) = x² - 16.

{x | x ≠ -4 and x ≠ 4}
{x | x ≠ -3 and x ≠ 7}
{x | x ≠ 4}

i have tried photo math and such and can not get an answer

1/800 is the right answer

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

1. perpendicular

2. parallel

3. perpendicular

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
