Question

Consider the line y=1 x -1 and the point P=(2,0).

(a) Write the formula for a function d(x) that describes the distance between the point P and a point (x,y) on the line. You final answer should only involve the variable x. Then d(x) =

(b) d'(x)=

(c) The critical number is x= .

(d) The closest point on the line to P is ( , ).

Answer:Step-by-step explanation:d(x)=√((x-2)2+(y-0)²)

=√((x-2)²+y²)

=√((x-2)²+(x-1)²)

=√(x²-4x+4+x²-2x+1)

=√(2x²-6x+5)

D=d²(x)=2x²-6x+5
