7) f(x)= x(squared) - 5
12) F(x)= 1/4x(squared)
Find the coordinates of the vertex. Then give the equation of the axis of symmetry and the greatest value of the function.
13) g(x)= -x(squared) - 3x
17) f(x) = x - 2x(squared)

You can put this solution on YOUR website! Find the coordinates of the vertex, then give the equation of the axis of symmetry and the least value of the function.
7) f(x)= x(squared) - 5
VERTEX IS X=0,Y=-5
LEAST VALUE =-5
12) F(x)= 1/4x(squared)
THERE IS NO VERTEX FOR THIS...CENTER IS(0,0)
LEAST VALUE TENDS TO ZERO
Find the coordinates of the vertex. Then give the equation of the axis of symmetry and the greatest value of the function.
13) g(x)= -x(squared) - 3x =-(X+1.5)^2+1.5^2
VERTEX IS X=-1.5,Y=1.5^2=2.25
GREATEST VALUE= 2.25
17) f(x) = x - 2x(squared)=-2(X^2-0.5X)=-2(X-0.25)^2+2*0.25^2
VERTEX IS X=0.25,Y=2*0.25^2=0.125
GREATEST VALUE =0.125
