Help ASAP with the following problems-

1) D: all real/(-inf, +inf) R: all real/(-inf, +inf)

2) x 5 or (-inf, 5)U(5,+inf)

Step-by-step explanation:

1) This is a linear equation, meaning that it has all real numbers all throughout.

This implies that you can plug in any x value and it will have a definite y value.

Domain is all reals or (-inf, +inf)

Range is all reals or (-inf, +inf)

2) We can see that if you plug in the number 5 for x, you would get 5-5 = 0 for the denominator. We can not divide a number by 0, therefore the domain is

x can not equal to 5 or (-inf, 5)U(5,+inf)
