Step-by-step explanation:

Answer 2

Answer:

B

Step-by-step explanation:

($\frac{f}{g}$)(x)

= $\frac{3x+5}{3x^2-x-10}$ ← factor denominator

= $\frac{3x+5}{(x-2)(3x+5)}$ ← cancel (3x + 5), leaving

= $\frac{1}{x-2}$

The denominator cannot be zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the value that x cannot be.

solve x - 2 = 0 ⇒ x = 2 ← excluded value

domain is the set of all real numbers except 2
