Question
Which function is represented by the graph below?
On a coordinate plane, a curve opens up and left in quadrants 1 and 2. The curve approaches the negative x-axis as an asymptote in quadrant 2, curves up, going through (0, 1), and increases rapidly in quadrant 1 passing near (4, 7).

The description you've provided suggests a function that has a specific shape and behavior. Based on the characteristics you've noted:
1. The curve opens up towards the left and approaches the negative x-axis as an asymptote, indicating it might be a type of inverse function or logarithmic function.
2. It passes through the point (0, 1), which suggests that when \( x = 0 \), \( f(x) = 1 \).
3. It increases rapidly in quadrant 1, suggesting that it has a steep positive slope.
Given all this information, a likely candidate for the function is:
\[ f(x) = -\frac{1}{x} + 1 \]
Here's why:
- As \( x \) approaches 0 from the positive side, \( f(x) \) approaches 1, aligning with your note about it passing through (0, 1).
- As \( x \) approaches negative infinity, \( f(x) \) heads towards the negative x-axis (y = 0), which matches the asymptote you mentioned (horizontal asymptote at y = 0).
- The rapid increase in quadrant 1 corresponds to the behavior near \( (0, 1) \) moving towards the right.
Thus, if the curve represents a common form as described, it resembles a transformation of a hyperbola or similar behavior indicative of the function mentioned. Depending on the exact details (like whether it's a transformation or a shift), this could be a correct representation; however, vertical or horizontal stretches may need consideration.
