Answer:
linear function, growth factor of 4
Step-by-step explanation:
The graph has the shape of a straight line, so it is linear.
The graph starts at point (0, 0). It passes through point (1, 4).
slope = (y2 - y1)/(x2 - x1) = (4 - 0)/(1 - 0) = 4/1 = 4
The slope is 4. Growth factor is the same as slope for a linear function.
