3.05: Compare Models Which description compares the domains of Function A and Function B correctly?

Function A: f(x)=(−x)−−−−√

Function B:

The domain of Function A is the set of real numbers greater than 0.

The domain of Function B is the set of real numbers greater than or equal to 0.

The domain of both functions is the set of real numbers less than or equal to 0.

The domain of Function A is the set of real numbers greater than 0.

The domain of Function B is the set of real numbers less than or equal to 0.

The domain of both functions is the set of real numbers greater than or equal to 0.

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
