Question

Find the domain of f/g.A.B.C.D.​

Answer 1

Answer:

C. All real numbers except $\frac{3}{4}$.

Step-by-step explanation:

The domain of all polynomials is the set of all real numbers, whereas the domain of rational-polynomic functions are the set of all numbers expect for those values of $x$ so that denominator becomes zero. Hence, we need to solve for $x$ from following expression:

$4\cdot x - 3 = 0$

$4\cdot x = 3$

$x = \frac{3}{4}$

The domain of the function is all real numbers except $\frac{3}{4}$. (Right answer: C)
