1. Sketch a graph the function Ax) = 3* . Identify the key features. a) domain and range b) any intercepts c) intervals for which the function is increasing and intervals for which it is decreasing 4 2 4 -2 0 2 4

1. Determine whether the relation represents a function. If it is a function, state the domain and range. 3 15 OA OC 25 A) function domain:(15, 20, 25, 301 range: (3, 4, 5, 6) B) function domain: (3, 4, 5, 6) range: [15, 20, 25, 30) C) not a function

a) Determine increasing intervals (slop) of the function if it exists. b) Determine decreasing intervals (slop) of the function if it exists.
