Solve the logarithmic equation and express the solution in exact form (no decimals or rounding). log4(x + 1) + log4(x – 1) = 2SHOW WORK: This problem requires you to show work on your paper. At the end of the test, scan and upload work to the last problem.

Select/Fill-in-the-Blank: Given y = logb x, if 0 < b < 1, then the graph is [a]

Fill-in-the-Blank: The graph of y = logb x passes through the point (1, 0) and the line  [a] is a [b] asymptote.

Signals below 20 degrees are likely to be less noisy than those above 20 degrees relative to the horizon.
