The vertex is #(0,0)#

Convert this equation to vertex form:

#f(x)=x^2#

#f(x)=(x+0)^2#

#f(x)=(x+0)^2+0#

#f(x)=(x-h)^2+k -> vertex -> (h,k)#

Or use the expressions: #(-b/(2a),f(-b/(2a)))#

#f(x)=ax^2+bx+c#

#f(x)=x^2#

#f(x)=x^2+0x+0#

#a=1, b=0, c=0#

#x=-b/(2a)=-0/(2(0))=0#

#y=f(-b/(2a))=f(0)=(0)^2=0#

#vertex -> (0,0)#
