Answer:
Roots = { 2, 5}
Vertex = (3.5, - 2.25)
Step-by-step explanation:
Roots
From the graph
x = {2, 5}
From factoring the equation
(x - 2)(x - 5) = 0
x = {2, 5}
--------------------------
The equation turns at the vertex
From the graph
(3.5, -2.25)
From the equation
X coordinate of vertex
x = -b/2a
x = 7/2 = 3.5
y = (3.5)² - 7(3.5) + 10
y = 12.25 -24.5 + 10
y = -2.25
