Answer:
Below
Explanation:
Use quadratic formula with a = -5 b = -10 c = 6
to find the zeroes x = -1 + sqrt(55) / 5 and -1 - sqrt(55)/5
the vertex is exactly between these two x values (due to symmetry)
add together and divide by two to get the x value of the vertex:
x = -1 use this value in the equation to get the y coordinate of the vertex = 11 vertex = -1,11
Axis of symmetry is the x value of the vertex x = -1
y intercept occurs when x = 0 plug that into the equation to find y = 6
Here is the graph:
