Answer:
x = -7/2 is not in the domain
Step-by-step explanation:
The numbers that must be excluded from the domain are the ones that make the function be undefined. That is, any value of x that makes the denominator zero will be excluded from the domain.
2x +7 = 0
2x = -7
x = -7/2 . . . . . must be excluded
The only number not in the domain is x = -3.5.
