What is the vertex of # y= x^2 - 4x - 3#?

Question:

What is the vertex of # y= x^2 - 4x - 3#?

Answers

#(2,-7)#

Explanation:

#(-b)/(2a)# is the #x# value for the maximum/minimum (vertex) of a quadratic graph. Work out what this value is and put it into the equation to find the #y# value.

#(--4)/(2)#=#4/2#=2 #x=2#

#=># #y=2^2-4xx2-3#

#=># #y=4-8-3#

#y=-7#
