Question 553079: Use a graphing calculator, graph the pair of functions y=square root 49-(x-2)^2 and - square root -(x-2)^2
a. identify the conic section represented by the graph
b. write its equation in standard
And the multiple choice is
a. circle;(x+2)^2+y^2=49
b. circle;(x-2)^2+y^2=49
c. ellipse;(x-2)^2/(4)+(y^2)/(49)=1
d. ellipse;(x-2)^2(49)+(y^2)/(4)=1

Use a graphing calculator, graph the pair of functions
y = square root[49-(x-2)^2] and
y = -square root[48-(x-2)^2]

------------------------------------------------

a. identify the conic section represented by the graph
circle
b. write its equation in standard
And the multiple choice is "b"
a. circle;(x+2)^2+y^2=49
b. circle;(x-2)^2+y^2=49
c. ellipse;(x-2)^2/(4)+(y^2)/(49)=1
d. ellipse;(x-2)^2(49)+(y^2)/(4)=1
