Problem 1. (1 point) Problem 4. (1 point) The domain of the function Let 2x h (x) = - f(x) = v5-6x. x2 - 81 Use interval notation to indicate the domain of f(x). is Note: Write the answer in interval notation. If the answer in- Domain = cludes more than one interval write the intervals separated by the 'union" symbol, U. If needed enter -co as - infinity and co as infinity . An embedded You Tube video.

Find f(x + h). f ( x th ) = Part 2 Part 3 Answer(s) submitted: Problem 5. (1 point) Let f(x) = *. Evaluate the following. If the answer is unde- fined, write "UND" (incorrect) (a) f(3) = Problem 3. (1 point) (b) f (7 ) = The domain of the function (c) f(4) = f (x) = *+4 Answer(s) submitted: x+2 is the set of all real number except and its range is the set of all numbers except Hint: To find the domain observe that we can't divide by zero. To (incorrect) find the range solve an equation for x. An embedded YouTube video. If the video does not work, click here to go to YouTube directly. Answer(s) submitted: (incorrect)
