Answer
Both functions have the same maximum
-value.
Solution
To analyze the
-values of the functions
and
, let’s examine each function:
-
Function
: - As
increases, grows exponentially, making decrease rapidly. Therefore, approaches 2 as approaches infinity. - As
approaches negative infinity, approaches 0, so approaches 2 from below. - The maximum
-value of occurs at and is equal to 2.
- As
-
Function
: - This is a downward-opening parabola. The maximum
-value occurs at the vertex. - The vertex of a parabola given by
is at . Here, and , so the vertex is at . - Evaluating
. Thus, the maximum -value of is also 2.
- This is a downward-opening parabola. The maximum
Now, let’s evaluate the options:
A.
has the largest possible
-value.
- This is false; both functions have the same maximum
-value of 2.
B.
and
have equivalent maximum
-values.
- This is true; both have a maximum
-value of 2.
C. The maximum
-value of
approaches 2.
- This is true, but it is not the most precise statement since the maximum
-value is exactly 2.
D.
has the largest possible
-value.
- This is false; both functions have the same maximum
-value.
Based on this analysis, the best answer is:
B.
and
have equivalent maximum
-values.

The Deep Dive
Did you know that the function
exhibits an interesting behavior? As
increases,
rapidly decreases towards negative infinity, which means that the
-values will approach 2 but never actually reach it! So, the maximum
-value of this function is indeed 2, confirming option C.
On the flip side, take a look at
. This quadratic function is a downward-facing parabola! Its maximum value occurs at the vertex, which can be calculated to be 2 as well, confirming that both functions reach their highest
-value of 2. So, both
and
have the equivalent maximum
-values, supporting option B!
