Question #14160

Answer 1

D) -1, -7 & 7 only

Explanation:

`1/((m^2-6m-7)/(m^2-49))`

=`1/{[(m+1)(m-7)]/[(m-7)(m+7)]}`

The function is defined in its domain, thus any values outside the domain will make the function undefined. It is crucial to determine the domain and or restricted values in the original format and before any simplifications, so in this case:
`m=-7,-1, 7` are all outside the domain thus will make the function undefined.
