5. Let g(x) = x2 + 2x +3. Complete the following: ( - 1,2 ) (a) Determine the vertex, axis of symmetry, and intercepts (simplified as much as possible), if any. Vertex: Axis of Symmetry: x 4 26 + 3 =0 2 x-intercept(s): 5 - 4 ac y-intercept : (01 3 ) X + 1) +2 The y intercept is axis of (2) 2 - 4 ( 1) ( 3 ) x '+ 2 4+ 3 = 0 if left symetric is 4-12=-8
