What is the vertex form of #y=x^2 - 4x + 14 #?

Answer 1

Eva Adamson

#y = 1(x-2)^2+10#

Complete the square to rearrange into vertex form:

#y = x^2-4x+14#

#=x^2-4x+4+10#

#=(x-2)^2+10#

#=1(x-2)^2+10#

The equation:

#y = 1(x-2)^2+10#

is in the form:

#y = a(x-h)^2+k#

which is the equation of a parabola with vertex at #(h,k) = (2,10)# and multiplier #1#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
