Which of the following is true with respect to the following functions: 1x) =3124141 g(x) = x + 3x2 - 14 t(x) = 3 + 1 1x) = log, 1x + 1) O A. The range of i(x) includes lesser (more negative) yvalues than the ranges of f(x), g(x), or h(x). B. The domains of g(x) and h(x) include all real numbers while the domains of i(x) and h(x) are restricted. O c. i(x) and h(x) are inverse functions. D. f(x) increases the most rapidly. ​

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e.g. 98.765).

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
