Take a look at f(x) = -x + 1. Its slope is negative and its y-intercept is +1.
Right away, we can eliminate the 3rd and 4th graphs, because they show positive slopes for x≤1.
Take another look: f(x) = -x + 1. When x = 0, y = 1. Thus, the y-intercept is (0,1).
The first graph shows this intercept correctly; the second does not. So the correct answe is "the first graph."
Answer: ok 28 times 28 gves 784 .

Small (x)
9(x) + 9(x) - 1 = 30
2 x 9(x) - 1 = 30
2 x 9(x) = 30 + 1
2 x 9(x) = 30
simplify
9x = 31/2
x = 1/2 x log (3) (31/2)
or
x ≈ 1.24741
The selling price is 2.5 times the cost. If the cost goes up by 0.25, the selling price needs to go up by 2.5*0.25 = 0.63 in order to maintain the gross margin.
