(Q1) Which is the graph of the catenary y=e^x+e^-x/2

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.
