A8-15.2 Graphing Logarithmic Functions

Graph the logarithmic function z(x) = -log x + 7. Find the asymptote. Then describe how the graph is transformed from the graph of its parent function.

• [Graph] Asymptote: x = 0. The graph z(x) is a translation down 7 units and a reflection across the x-axis of the parent function f(x) = log x.

• [Graph] Asymptote: x = 7. The graph z(x) is a translation left 7 units and a reflection across the y-axis of the parent function f(x) = log x.

• [Graph] Asymptote: x = 0. The graph z(x) is a translation up 7 units and a reflection across the y-axis of the parent function f(x) = log x.

• [Graph] Asymptote: x = 0. The graph z(x) is a translation up 7 units and a reflection across the x-axis of the parent function f(x) = log x.

Match the graph with its equation

• y = log₆(-x) + 1
• y = log₆(x − 2) + 1
• y = log₆(x + 2) - 1
• y = log(x-8) + 1
