Question 111670: i need help.
use the graph of y=-x^2+4x+5 to answer the following. all these are under 1 question.
1.using the graph, what are the solution(s)to the equation -x^2+4x+5=0?
2.Does the fuction have a maximum or a minimum?
3.what are the coordinates of the vertex in (x,y)form?
4.what is the equation of the line of symmetry for this graph?

Graph the quadratic equation:

From the graph:
1) The roots are: x = -1, x = 5
2) The function has a maximum.
3) The vertex is at (2, 9)
4) The equation of the axis (line) of symmetry is: x = 2
