x-3
____
x-7

Answer 1

it's undefined when denominator =0. solve for value of x if denominator =0. that's the answer

Answer 2

i still dont understand?

Answer 3

look at this: \(\frac{1}{x}\). for which \(x\) is this fraction undefined?

Answer 4

The denominator is (x - 7).

The function is undefined when the denominator is equal to zero, because you aren't allowed to divide by zero.

So what value of x fulfills the following statement? (x - 7 = 0)

Answer 5

i dont know. i dont get this at all.
