Given an arithmetic sequence in the table below, create the explicit formula and list any restrictions to the domain.. a_n = 40 + 7(n − 1) where n ≥ 40 . a_n = 40 + 7(n − 1) where n ≥ 1 . a_n = 40 − 7(n − 1) where n ≥ 40 . a_n = 40 − 7(n − 1) where n ≥ 1 .

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

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

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)
