What is the effect on the graph of the function f(x)=x when f(x) is replaced with -1/2f(x)?

The line will change its slope by a factor of -2 (line will now "point down" with twice the original steepness)

Step-by-step explanation:

f(x) = x    | replace f(x) --> (-1/2)f(x)

(-1/2)f(x) = x

f(x) = -2x

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%
