For thefunctionf(x)= -1/2(x + 5)^2 + 8
What is the Vertex?
(-5, 8)
What is theAxis of Symmetry?
x=-5
Describe the max or min value of the function?
maximum is 8
What is the y-intercept?
f(0)=-(1/2)*5^2+8=-9/2
What equation would you solve to find the x-intercepts of the function? Draw a graph.
-(1/2)*(x+5)^2+8=0
So,
x=-1 or x=-9
