Part 1. using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are inverses. f(x)= x+a b g(x)=cx−d
part 2. show your work to prove that the inverse of f(x) is g(x).
part 3. show your work to evaluate g(f( part 4. graph your two functions on a coordinate plane. include a table of values for each function. include five values for each function. graph the line y = x on the same graph.

Rewrite the expression in z to the n power. the expression i was given is: 1 over z to the negative 1 half power.

Consider the linear model for a two-stage nested design with b nested in a as given below. yijk=\small \mu + \small \taui + \small \betaj(i) + \small \varepsilon(ij)k , for i=1,; j= ; k=1, assumption: \small \varepsilon(ij)k ~ iid n (0, \small \sigma2) ; \small \taui ~ iid n(0, \small \sigmat2 ); \tiny \sum_{j=1}^{b} \small \betaj(i) =0; \small \varepsilon(ij)k and \small \taui are independent. using only the given information, derive the least square estimator of \small \betaj(i) using the appropriate constraints (sum to zero constraints) and derive e(msb(a) ).

When a number is decreased by 9.9% the result is 40. what is the original number to the nearest tenth? super urgent
