Hi, need some help. Thank you.

2. evaluates a function. Evaluate the ff: a. f(x) = 6x -8, at x = 4 b. P(x) = x2+5, at x = 5 5. solves rational equations and inequalities. Solve the rational equation/inequality below. Show the complete solutions: a. 8/(r+1) = 4/3 b. (r+3)/3x-6 >0 6. represents a rational function through its: (a) table of values, (b) graph, and (c) equation. Find the domain and range of y = (r+1)/(-1)
