Question

the graph above is a continuous line or curve. its domain can best be described as a subset of the whole numbers. for every unit that ( x ) increases, the ( y )-value grows or declines by repeated multiplication. as a result, the graph can best be said to represent
options: an arithmetic sequence, a geometric sequence, a linear function, an exponential function

Explanation:

1. Arithmetic sequences have constant addition of a common difference, not multiplication, and are discrete (not continuous lines/curves).
2. Geometric sequences involve repeated multiplication but are discrete (defined only for whole number inputs, not a continuous domain).
3. Linear functions change by a constant addition (slope) per unit x increase, not multiplication.
4. Exponential functions are continuous, can have a domain of real numbers (a superset of whole numbers), and change by repeated multiplication of a base value for each unit increase in x.

Answer:

an exponential function
