Select the correct answer. Suppose the perimeter of a rectangle is 4 units, where \;l\;l is the length and \;w\;w is the width of the rectangle. Therefore,

w=2l

l=2+w

l+w=1

w=2+l

l=2-w

Select the correct answer. The quadratic function which has a vertex \;(h,k)=(1,4)\;(h,k)=(1,4) and contains the point \;(x,y)=(2,6)\;(x,y)=(2,6) is

f(x)=(x-1)^2+4

f(x)=x^2+3x+2

f(x)=2x^2-4x+6

f(x)=2(x+1)^2+4

f(x)=2(x-1)^2-4
