#1) \(Let f(x) = 4x - 7, g(x) = (x + 1)^2, and s(x) = f(x) + g(x). What is s(3)?\)?

[looking for s(3)]

#2) \(Let f(x) = 2x^2 + 3x - 9, g(x) = 5x + 11, and, h(x) = -3x^2 + 1. Find f(x) - g(x) + h(x).\)

#3) \(Let f(x) = 3x + 2 ,and, g(x) = x^2 - 5x - 1. Find f(g(x)).\)

#4) \(Let f(x) = 3(x - 6)^2 + 1. What, ,is, ,the, ,range, of, f? Express, your, ,answer, ,with, ,interval, ,notation.\)

#5) \(The function f(x) satisfies f(\sqrt{x + 1}) = \frac{1}{x}for all x \ge -1, x\neq 0. Find f(2).\)

Note: The commas were added for readability hopefully it helped read the problems better.
