Revolt · Accepted Answer

A: ✔ line A

Question 2

On the graph shown, line B is the parent functionf(x) = log10(x).Which function is graphed as line A?

Revolt · Accepted Answer

D: g(x) = log10 (x) + 3

Question 3

On the graph shown, line C is the parent functionf(x) = log2 (x).Which function is graphed as line D?

Revolt · Accepted Answer

A: g(x) = log2 (x) – 1

Question 4

Consider the graphs f(x) = log10x and g(x) = a · log10x.What happens to the graph of g(x) = a · log10x if a is –7? Check all that apply.The graph is stretched vertically.The graph will shift a units to the right.The graph is compressed.The graph is reflected across the x-axis.The graph will shift a units to the left.

Revolt · Accepted Answer

A: The graph is stretched vertically.; D: The graph is reflected across the x-axis.
