Which statement best describes the domain of the function f(x)=3x/4x^2-4 all real numbers all nonzero numbers all real numbers except x=3/4 all real numbers except x=1 and x=-1

The correct answer is D. All real numbers except x = 1 and x = -1

Step-by-step explanation:

Domain : It consists of all the set values for which any function f(x) is defined or for which value the given function f(x) exists

The function f(x) is given to be :

The domain is all real numbers except the singularities of the denominator.

⇒ 4x² - 4 = 0

⇒ 4x² = 4

⇒ x² = 1

⇒ x = ±1

Thus, The correct answer is D. All real numbers except x = 1 and x = -1

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
