Final answer:

The y-intercept of f(x) is 3, and the y-intercept of the linear function g is 9. To calculate the distance between them, we subtract one from the other, resulting in a distance of 6 units, which does not match any of the given answer choices.

Step-by-step explanation:

The y-intercept of the function f(x) = 2x^2 - 6x + 3 is the y-coordinate of the point where the graph of the function intersects the y-axis. This occurs when x=0, thus plugging x=0 into the function gives f(0) = 2(0)^2 - 6(0) + 3 = 3. Therefore, the y-intercept of f(x) is 3.

According to Figure A1, the y-intercept of the linear function (g) is 9. To find the distance between these two y-intercepts, we simply subtract the smaller y-intercept from the larger one: 9 - 3 = 6.

The distance between the y-intercepts of the two functions is 6 units, which is not one of the provided options (A: 2 units, B: 3 units, C: 8 units, D: 9 units). Therefore, it seems there may be an error in the provided options.
