From the graph, we can see that the quadratic function opens upward and the vertex is (1, -3) Question 6. x = 2 f(t) = -16t + 80t + 5 Given, Range: 0 f(x) 25. c. Compare the graphs. substitute: Answer: = 11, Question 6. x2 4x 13x + 52 = 0 Answer: Answer: Question 4. Explain your reasoning. Work with a partner. y = x2 36 The height (in meters) of a bird diving to catch a fish is represented by h(t) = 5(t 2.5)2, where t is the number of seconds after beginning the dive. when b = 0 Describe the transformation from the graph of f to the graph of g. Then graph f and g in the same coordinate plane. f(x) = a(x p)(x q)(x r) f(x) = -5(x + 7)(x 5) Classify each system of equations by the number of solutions. (-2r + 6s)(-2r 6s) Set up 2 equations using the points a = 4 and b = -3 g(x) = -4x2 8x 4 -2 = a(1) x(x 1) = 0 Explain why the average rate of change of a linear function is constant and the average rate of change of a quadratic or exponential function is not constant. We are given that (119, 0) lies on the graph. Given equation We can see that in the consecutive y-values, each subsequent y-value is divided by 4. b = 1/4 How does the graph of y = ax2 + c compare to the graph of y = ax2? VOCABULARY (1, 3n 1), (2, 10n + 2), (3, 26n), Graph the function above and graph y = x2 Search the history of over 804 billion f(x) = a(x p)(x q) = 20 9 How much should the store charge to maximize monthly revenue? (-3, 8), (-2, 4), (-1, 2), (0, 1), (1, 0.5) Answer: x = undefined because of division by 0. We also can see that the functions y-intercepts is 123, Answer: b. f(t) = -16(t2 + 2 . y = a . Now we have to substitute x = -2 in the above expression where (4, 0) and (6, 0) are zeros 2. Question 7. The error is that the graph g(x) = x2 10 is the graph of f(x) = x2 translated down by 10 units instead of up. The Big Ideas Math: Modeling Real Life series comes with two options of accelerating students, the Advanced Pathway and the Compacted Pathway. x = 9/2(-$\frac{3}{4}$) Given, a = -1 f(8) = f(7) + f(6) = 13 + 8 = 21 They are listed in the following fashion. Answer: Question 38. Answer: f(x) = $\frac{1}{4}$(x 6)2 Question 5. -1 = a 4 b. Graph the function using the domain in part (a). The system is inconsistent. As the function is increasing, the rate of change also increases. Access the free Student Edition of your textbook by selecting your program from the drop-down menu. (-4, -4), (-2, -3.4), (0, -), (2, -2.6), (4, -2) HOW DO YOU SEE IT? y = 3000(1.2)t f(x) = (x + 2)(x 6) Essential Question What are some of the characteristics of the graph of a quadratic function of the form f(x) = ax2? 25 feet, 13 ) t ( x ) = h ( x q ) 0:!
