Identify all the transformations of f(x)=14⋅3x+5+8

from its parent function. In 3-5 good sentences, describe all transformations.

1 answer

The parent function of \( f(x) = 14 \cdot 3^{x+5} + 8 \) is the exponential function \( g(x) = 3^x \). The function undergoes several transformations:

  1. Horizontal Shift: The term \( x + 5 \) indicates a horizontal shift to the left by 5 units.
  2. Vertical Stretch: The coefficient \( 14 \) in front of \( 3^{x+5} \) means the graph is vertically stretched by a factor of 14, making it grow faster than the parent function.
  3. Vertical Shift: The addition of \( 8 \) at the end moves the entire graph upwards by 8 units.

Combining these transformations, the graph of \( f(x) \) is first shifted left by 5 units, then stretched vertically by 14, and finally moved up by 8 units.
