Determine the domain of the function y 72x6 Select one a

Determine the domain of the function y = 7/(2x+6 ) Select one: a. (-, -3) U (-3, ) b. (-, 3) U ( 3, ) c. (-, -7) U (7, ) d. (-, 7) U (7, )

Solution

y = 7/(2x+6 )

where 2x+6 is not equal to 0

    x is not equla to -3

domain is set of real numbers except x=-3

domain (-, -3) U (-3, )

answer is \'A\'
