Use the domain {½,1,2,4,8} to plot the points on the graph for the given equation. the grid marks represent one unit, the horizontal red line represents the x-axis, and the vertical red line represents the y-axis.
y = log 2 x

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126
