We can't tell from the graph whether the left point of each step is included, or the right point. If the left, this is a graph of
y = 7 + floor(x)
45 degrees.
To find the central angle or angle of rotation divide 360 (degrees in a circle) by the number of sides (octogon=8) 360/8=45
Y=5(2^x)
It Would be the first graph of the choices.
Hope this helps!
Im sorry if this is wrong but I thinks the answer is...
