1 . Determine the sum. (Show. The y-intercept of a function can be found by letting x = 0. The y-intercept should be expressed as coordinate point. What is the y-intercept of the function f (x) = 8ln(x + ez) + 1? Show your work. Solve the equation: log, (52 - 2x) - log7(x + 1) = 2 Show all work. (Express answer as a fraction in simplest terms.)
