Question

Explain why there are restrictions on the domain for the function, f(x)= 1/x-7

Answer 1

Yes.

Explanation:

Because if x = 7 the denominator (x - 7) will be zero and the function would have no value. So the domain is All real x except x = 7.

Answer 2

Yes , there is restriction on the domain for the function, f (x) = 1/(x- 7)

For explaining it i want to give a example to you.

Let us put x = 7,

Then we get,

f (x) = 1/(7-7)

= 1/0

It is indeterminant form or not defined form☝

So we cannot put x = 7 in this function.

And as we know that the values we put is called domain.

Therefore, there is restriction on uts domain.
