Answer:
a.
Step-by-step explanation:
A catenary looks a lot like a parabola. Only graph "a" has that appearance.
___
A graphing calculator can help you choose, or you can recognize the nature of the terms of the sum.
e^x looks like graph D; e^-x looks like graph B. Their sum will always be positive, so cannot create graph C. At x=0, the average of the two graphs B and D will be 1, corresponding to the minimum of graph A.
First use the distance formula to find the radius of the circle:
d=
d=
d=
d=
d=
d=|17|
d=17
Next, find the equation of the circle (use the first picture):
(x+1)^2+(y-5)^2=17^2
Finally, input the equation into a graphing calculator:
