The simple linear regression model is $Y = \beta _ { 0 } + \beta _ { 1 } x + \varepsilon \text {, where } \varepsilon$ is a random variable assumed to be normally distributed with $E ( \varepsilon ) = 0 \text { and } V ( \varepsilon ) = \sigma ^ { 3 } \text {. Let } x ^ { + }$ denote a particular value of the independent variable x. Which of the following identities are true regarding the variance of Y when $x = x ^ { + }$ ?
