Math Problem Statement

If function f is the parent exponential function f(x) = e^x, what is the equation of the transformed function g in terms of function f? Replace the value of a to complete the equation.

Solution

From the graph you provided and the base function f(x)=exf(x) = e^x, it appears that the transformed function gg involves a vertical stretch and possibly a horizontal shift.

Analyzing the Graph:

  • The graph passes through the point (0, 3), indicating a vertical stretch.
  • The original function f(x)=exf(x) = e^x passes through (0, 1).

Transformation Observation:

  • Given g(x)=aexg(x) = a \cdot e^x and g(0)=3g(0) = 3, substituting x=0x = 0 into the transformation, we have: ae0=3a \cdot e^0 = 3 a1=3a \cdot 1 = 3 So, a=3a = 3.

Concluding the Equation: The equation of the transformed function gg in terms of the function ff is: g(x)=3f(x)=3exg(x) = 3f(x) = 3e^x

Would you like to know more about how transformations affect the graph of exponential functions, or do you have any other questions on this topic? Here are some follow-up queries you might find helpful:

  1. What would the graph look like if we also shifted g(x)g(x) horizontally?
  2. How do reflections across the x-axis or y-axis affect the graph of f(x)=exf(x) = e^x?
  3. Can you explain the effect of changing the base of the exponential function from ee to another base like 2 or 10?
  4. How would adding a vertical shift modify the equation and graph of g(x)g(x)?
  5. What is the effect of a horizontal compression on the graph of an exponential function?

Tip: When analyzing transformations of functions, always consider how each transformation—shifts, stretches, compressions, and reflections—affects the original graph in both shape and position.
