To graph , shift the graph of 2 units to the left and 2 units upward.

Solución

  1. Begin with the graph of . This is an exponential curve that passes through the point , has a horizontal asymptote on the -axis, and increases as increases.
  2. Consider the function .
  3. Notice that the function can be seen as applying two transformations to :
    • The term inside the exponent indicates a horizontal shift. Since the term is , the graph shifts 2 units to the left.
    • The outside the exponential function indicates a vertical shift. The graph moves 2 units upward.
  4. Therefore, the graph of is horizontally shifted 2 units to the left and vertically shifted 2 units upward to obtain the graph of .
  5. The correct choice is:
    A. The graph of should be horizontally shifted 2 units to the left and vertically shifted 2 units upward.

To graph the function , we start with the parent function . The expression indicates a horizontal shift to the left by 2 units. Adding 2 to the function moves it vertically upward by 2 units. Thus, the correct transformation is that the graph of should be horizontally shifted 2 units to the left and vertically shifted 2 units upward.
So, the answer is A. The graph of should be horizontally shifted 2 units to the left and vertically shifted 2 units upward.
Now, let’s add a little fun and context to our exploration of exponential functions!
Exponential functions, like , start off slowly and then shoot up dramatically, given their unique nature! You might want to think of them as a child at a birthday party—starting off shy but getting more jubilant as they’re surrounded by joy (or in this case, as increases).
When transforming graphs, it’s crucial to keep a sharp focus on how each parameter affects the graph! Many learners tend to overlook the signs in transformations, but remember this: a positive in the equation means a shift left and down, while a negative signifies a shift right and up. This little nugget might help you dodge common pitfalls!
