On the image of exponential function in the first year of high school I did an exponential function image problem, a belongs to 1 / 3, 1 / 2, 2, 3, ask which of these four images is, I have no graph, please tell me when a is greater than 0 and less than 1, is a = 1 / 3 close to the Y axis, or 1 / 2 closer to the Y axis, when a is greater than 1, is a = 2 closer to the Y axis or 3 closer to the Y axis

When a is greater than 0 and less than 1:
A = 1 / 3, that is, the image of y = a ^ x is closer to the y-axis,
But the images of y = (1 / 3) ^ x, y = (1 / 2) ^ x all pass through the point (0,1)
When a is greater than 1:
A = 3, that is, the whole image of y = 3 ^ x is closer to the Y axis,
But the images of y = 3 ^ X and y = 2 ^ x all pass through the point (0,1)
