Use the graph of f(x)={x+3,x<−1−4x−2,x≥−1. The graph with X-coordinate marks -4, -2, 0, 2, 4 and Y-coordinate mark -4, -2, 0, 2, 4. There is function f which starts intersects y-axis at (0, -2), and the x-axis at (-0.5, 0), then it increases till (-1, 2) then decreases and intersects x-axis at (-3, 0).

Over what part of the domain is function f increasing?

A. x < −1
B. x ≥ 2
C. x ≥ −1
D. x < 2

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
