Find the excluded value(s) of the rational expression . 1. Set the denominator equal to 0. 3x2 48 = 0 2. Solve for x. 3x2 = 48 x 2 = 16 What value(s) for x will make the rational expression undefined? a 16 b 4 c 2, 3 d 0
2 answers:
Answer:
B. 4
Step-by-step explanation:
We have the equation x^2 = 16 and we want to solve for x.
Square root both sides:
x = +/- 4
A rational expression is considered undefined when the denominator is equal to 0 (in other words, we get something like k/0, which is undefined). Here, the because when x = 4, then the answer is B.
Hope this helps!
Answer:
b 4
Step-by-step explanation:
The function becomes undefined when the denominator goes to 0
3x² - 48 = 0
3x² = 48
x² = 16
x = +/ 4
From the given choices, it's x = 4
