The functions f and g are defined as follows: f(x)= -4x +7 and g(x) = 5x2 - 13. Find f(5) and g(-3).3. Marco plans to save $54 per week to low,I a new laptop worth $1296. The amount. A (in dollars) that he still needs after w weeks is given by the following function. A(w) = $1,296 54w Answer the following questions. a. How much money does Marco still need after 11 weeks? b. If Marco still needs $216, how many weeks has he been saving? 4. Graph Hie function x) = 112- 1 5. Use the quadratic formula to solve 338 +5): = 7' Round your answer to the nearest hundredth. 6. Graph the function f(x} = 2x2 7. Graph the parabola y = (x -2) +4 8. A coffee supply company roasts coffee and supplies the roasted coffee to regional stores. The unit cost C (the cost in dollars to make crate of coffee) depends on the number of pounds of coffee roasted. If x pounds are roasted, then the unit cost is given by the function C(x) = 0.7x2 - 42x + 1234. What is the minimum cost? Do not round your answer.9. The graph of a function is given below. Give all x-intercepts and y-intercepts shown. 5 -10 -5 0 5 10 -10 If there is more than one answer, separate them with commas. x-intercept(s): v-intercepts(s):\f
