Show Hint
The Correct Option is A
Solution and Explanation
Option (1): upward-curving exponential rise, correct. Option (2): straight line, not exponential. Option (3): curve that flattens (concave down), wrong. Option (4): decreasing curve, wrong.
Answer: (1) the graph of k rising exponentially (curve bending upward) with T
