For X=0 Y=2.
As x increases, y decreases, but will never become 0.
As x decreases, y increases rapidly.
Try several positive and negative data points for x, such as x =2, x=4, x=6 and x=-2 x=-4 and x=-6
You'll see a smooth curve.
For the family of curves Y=cax, where c is a constant and a is any real number, for a value of a=1 the graph is parallel to the x-axis, since 1 to any power is always 1.
Any value of a>1 will give a graph which is concave up and pointed to the right.
Any value of a>1 will give a graph which is concave upward and pointed to the left.
The y intercept will always be c.
