Question 368606: find vertex and axis of symmetry
+g%28x%29=x%5E2%2B5x%2B4+
so far I've done...
+%28x%5E2%2B5%29%2B4+
+%28x%5E2%2B5%2B6.25%29%2B%28-6.25%2B4%29+
+%28x%2B11.25%29%5E2-2.25+
vertex= (11.25, -2.25)
axis of symmetry= 11.25
not sure if my numbers are right!

find vertex and axis of symmetry
+g%28x%29=x%5E2%2B5x%2B4+
so far I've done...
+%28x%5E2%2B5%29%2B4+ ***5x
+%28x%5E2%2B5x%2B6.25%29%2B%28-6.25%2B4%29+
+%28x%2B11.25%29%5E2-2.25+ (x + 2.5)^2, not 11.25
vertex at -2.5,g(-2.5)
------------------------
vertex= (11.25, -2.25)
axis of symmetry= 11.25
