Increasing linear
Decreasing linear
Increasing exponential
Decreasing exponential
Explanation
Correct answer: A.
Choice A is correct. The graph of function shows that as increases, also increases, which means is an increasing function. The graph of is a line, which indicates a constant rate of change. A function that has a constant rate of change is a linear function. Therefore, function can be described as increasing linear.
Desmos solution:
Note: The graph shows a straight line with a positive slope, so the function is increasing linear.

Why the other choices are wrong
Choice B
Choice B is incorrect. For a decreasing function, as increases, decreases, rather than increases.
Choice C
Choice C is incorrect. The graph of an exponential function isn't a line.
Choice D
Choice D is incorrect. For a decreasing function, as increases, decreases, rather than increases, and the graph of an exponential function isn't a line.
