Betancourt, Daniel – Exam 3 – Due: May 1 2007, 11:00 pm – Inst: Diane Radin 12 6. Explanation: Let’s first review some properties of ln x and ln( - x ). Since ln x is defined only on (0 , ) and lim x 0 + ln x = -∞ , lim x → ∞ ln x = , the graph of ln x has a vertical asymptote at x = 0 and so is given by But then ln( - x ) is defined only on ( -∞ , 0) and has the properties lim x 0 - ln( - x ) = -∞ , lim x → -∞ ln( - x ) = , so its graph has a vertical asymptote at

Unformatted text preview: x = 0 and is given by Now the given Function is f ( x ) = log 3 ‡ 1 4-x · =-log 3 (4-x ) . Its graph will have a vertical asymptote at x = 4, and so will be that oF log 3 (-x ) translated 4 units to the leFt, then ‘±ipped over’ the x-axis. Consequently, f has graph keywords: graph, log Function, vertical aymp-tote, limit at infnity, absolute value Function...
