Functions f, g, and h are shown on the graph. Which of these functions have a domain of all real numbers?
A. Functions f and g only
B. functions g and h only
C. Functions f only
D. Functions f, g, and h

Option (D)

Step-by-step explanation:

Domain of a function is defined by the x-values (input values) of the graph.

Similarly, Range is defined by the set of y-values (output values) of the graph of the function.

From the graph attached,

Domain of function 'f' : {x | x ∈ R}

Domain of function 'g' : {x | x ∈ R}

Domain of function 'h' : {x | x ∈ R}

Therefore, all the function graphed have domain of all real numbers.

Option (D) will be the answer.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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%
