Question

What is the domain of the function H(w)=70/w

Answer 1

Domain = range of values of x

When w = 0, 70/w is undefined.
Other than that, all values of w are definable.

Hence, Domain = (-infinity, infinity), w =/= 0.

Answer 2

The function is not defined only when w=0.
So, R-{0}

Answer 3

@dauspex w=/=0 isnt one of the answer choices?

Answer 4

@koushik_ksv my answer choices are w > 0, w < 0, w < 1, w > 1

Answer 5

Then all the options are correct.
Are you sure about the question and its options?

Answer 6

Here is the exact question... The function describes the relationship between the height and the width of a rectangle with area 70 sq. units. The function is H(w)=70/w @koushik_ksv

Answer 7

So, there are restrictions on w naturally. It is length, so it cannot be negative.
You get it?

Answer 8

@koushik_ksv still not understanding, so it would be any one of the answer choices I showed you?

Answer 9

As w should not be negative,
Your 2 nd, 3 rd options are wrong.
The other two are good.

Answer 10
