Which of the following is a valid exclusion for the algebraic fraction 8ab^2x/4a^2b - 8ab^2
avanturin [10]

The valid exclusion of the algebraic fraction is (c) a =0, b =0, a =2b

<h3>How to determine the valid exclusion?</h3>

The expression is given as:

8ab^2x/4a^2b - 8ab^2

Set the denominator to 0

4a^2b - 8ab^2 = 0

Divide through by 4ab

a - 2b = 0

Add 2b to both sides

a = 2b

Hence, the valid exclusion of the algebraic fraction is (c) a =0, b =0, a =2b

What are the domain and range of the absolute value parent function?
dimaraw [331]

Answer:

Step-by-step explanation:

The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0).  There are no restrictions on the input, x, so the domain is (-infinity, infinity).

On the other hand, this function has no values less than zero.  Its range is

[0, infinity).
