identify the ff properties in the given quadratic equations:

a.Vertex b. axis of symmetry c. Domain
d. Range e direction of graph

1.f(x)=x2-5x+14

complete the square:

f(x)=x^2-5x+25/4 + 14-25/4
= (x-5/2)^2 + 7.75

so the vertex is at x=5/2, y=7.75
axis of symmetry x=5/2
domain all real x you do the rest. On the direction of the graph, what happens as x gets very large?
