- The graphing utility screen shows the graph of y = 4x2 - 8x + 7. a. Use the graph to describe the solution set of 4x2 - 8x + 7 > 0.b. Use the graph to describe the solution set of 4x2 - 8x + 7 < 0.c. Use an algebraic approach to verify each of your descriptions in parts (a) and (b).arrow_forwardThe bar graph shows discretionary spending by full and part-time college students in some country from 2007 through 2013. The data in the graph can be modeled by the formula D=1.2x +1.6(x+40), where D represents discretionary spending among students, in billions of dollars, x years after 2007. According to the formula, how much money did college students spend in 2007? Does the model underestimate or overestimate the amount of discretionary spending displayed by the bar graph? By how much?

- Let Y represent the total cost of publishing a book (in dollars) let X represent the number of copies of the book printed. Suppose that X and Y are related by the equation Y = 15x + 1250. answer the question below. note that a change can be an increase or a decrease. for an increase, use a positive number. For a decrease, use a negative number. what is the cost to get started (before any books are printed ) ? what is the change in the total cost for each book printed?arrow_forwardSolve 7x + 3 < 5x + 9.
