2)Write the equation of the parabola y= 4x^2-8x+1 in standard form

answer= y= 4(x-1)^2-3

3)Write an equation for the parabola with focus (1,3)and vertex(0,3)

answer= x= 1/4(y-3)^2

4)Write an equation for a circle if the endpoints of a diameter are at (1,1)and(1,-9)

answer= (x-1)^2+(y+4)^2=25

5)Which is the equation of a circle with center (0,1)and radius 2 units?

answer= x^2+y^2-2y=4
