Match the following log functions to their horizontal shift (which way will the asymptote shift)

• Shift Right

• No Horizontal Shift

• Shift Left

Write the equation of the graph.

• f(x) = log ₂(x) + 3

• f(x) = log₂ (x) - 3

• f(x) = log₂ (x+3)

• f(x) = log₂(x-3)

Identify the transformation that makes the graph shift horizontally to the left fifteen units.
