Find the axis of symmetry and the vertex of the graph of f(x) = -5x^2 +20x -9.
Answers
Answer:
Axis of Symmetry:
x=2
Vertex:
(2,11)
Step-by-step explanation:
Finding the derivative:
f'(x)=-10x+20
Setting the slope equal to zero:
-10x+20=0 x-2=0 x=2
Finding vertex:
f(2)=-5*(2)^2+20*2-9
=-20+40-9=20-9=11
