Which statement describes whether the function f (x) = StartFraction 8 (x minus 1) squared Over (x minus 8) squared EndFraction has a vertical asymptote at x = 8?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

The discrete random variables x and y take integer values with joint probability distribution given by f (x,y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x,y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
