Final answer:
To graph the function y - f(x) that satisfies the given properties, we need to find a function that decreases and has an increasing slope as x increases. Option b. y = x² satisfies these properties.
Step-by-step explanation:
To graph the function y - f(x) that satisfies the given properties, we need to find a function that decreases and has an increasing slope as x increases. Option b. y = x² satisfies these properties.
Let's plot the graph of y = x² to see if it matches the given properties:
- At x = 3, the function has a positive value (9).
- The slope of the function is positive and decreasing in magnitude with increasing x.
Thus, b. y = x² satisfies both properties.
