Rather than try to select the correct answer without doing work, I'd rather do the work first and the matching later.
Given y = 4 - x, or y = 4 - 1x,
1) the y-intercept is (0,4). 2) this being a linear function, it has neither maximum nor minimum. 3) the x-intercept is found by letting y = 0 and solving for x: 0 = 4 - x; x - 4. The x-intercept is (4,0).
We can deduce that the age distribution vector x represents the number of population members for each age class; Given that in each class of age there are 112 members present.
The current age distribution vector is as follows:
Also , the age transition matrix is as follows:
After 1 year ; the age distribution vector will be :
