8 Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function
2x2 + 4x -3.
O x = -2; vertex: (-2, -3)
O x = 1; vertex: (1, 3)
O x = -1; vertex: (-1, -5)
O x = -1; vertex: (-1, -7)

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.
