b.The graph will shift a units to the right.
c.The graph is compressed.
d.The graph is reflected across the x-axis.
e.The graph will shift a units to the left.

The answers are a.The graph is stretched vertically and d.The graph is reflected across the x-axis.
Since the parent function f(x) = log10x is multiplied by a constant a that is equal to -7, the result is a graph for 
     g(x) = -7 log10x
This is a vertical stretch of the graph of f(x) because |a|>1.
And since a = -7 is less than zero, the graph for g(x) = -7 log10x is reflected across the x-axis.
