2.1 (day 2) In each of the following graphs, a) tell whether or not each graph is a function and, b) identify the domain and range of each relation. 1. 2. 3. 4. 5. Find the domain of each function. Write the answer in interval notation. 6. 1 f x = x -1 7. f x = 3 x + 2 8. 2 x +5 g x = 7 9. x - 2 H x = x + 2 2.2 (day 1) I. Write the equation of the line in the following forms: a. point-slope form b. slope-intercept form c. standard form 1. slope = 1 2 and passes through the point (0, 4) 2. a line that passes through the points (-2, -3) and the origin 3. the x-intercept is 10 and the y-intercept is 2 4. a line passing through (4, 6) and parallel to the graph of y = - 2 3 x + 5 5. a line passing through (-2, 0) and perpendicular to the graph of y = -3x + 7 II. Answer the following. 6. Is the line x = 2 perpendicular to the line y = 3? 7. Is the line x = 3 parallel to the line y = 1/3? 8. Is the line y = 2 3 x 4 parallel to the line 3 y = - x - 4 2 ? 9. Are the lines 2x + 3y = 2 and 2x + 3y = 4 parallel? 10. Are the lines x 4y = 2 and 4x + y = 8 perpendicular?
