Use the following information to answer the question The partial graph of a quadratic function is shown below. Use the following information to answer the question. steps: Ming converts f(x) = 3x2 - 15x + 12 into vertex form by following Step 1 f(x) = 3(x2 -5x)+4 Step 2 ( (xx ) = 3 ( x2 - 5x + ( - 2 ) ? ) + 4- 3( - 2 ) 2 Step 3 f ( x) = 3 (x2 - 5x + (- 5) ? ) + 16 - 2 Step 4 3 - 2 1 ( x ) = 3( x + 5) - 50 The equation of the axis of symmetry of the given function is In which step did she make her first error? Select one: Select one: O A. x = -1 because the vertex is (-1, 2). O A. Step 1 because she should not have factored a three out of twelveas well . O B. x = 3 because the y-intercept of the function is 3. O B. Step 2 because she should not have multiplied (-) by three when O C. x = 0 because every quadratic function has an axis of symmetry moving it out of the brackets . x = 0. O C. Step 3 because (-2) = 25. O D. x = 2 because the vertex is (-1, 2). O D. Step 4 because (x + ) # x2 - 5x + (-= )? The vertex of the quadratic function f(x) = -2(x - 4)2 + 2 is Select one: It of O A. (4, -2) O B. (-4, -2) O C. (-4, 2) O D. (4, 2 ) Two numbers have a difference of 28. If the sum of the squares of the numb 392, what are the two numbers? The smaller number is: The larger number is A company that charters a boat for tours can sell 200 tickets at $25 each. For every $5 increase in the ticket price, 15 fewer tickets will be sold. Let R represent the revenue for the boat company. Let y represent the number of $5 ticket price increases. Write a quadratic function in factored form that represents the revenue earned. Select one: O a. R = (25+x)(200-x) O b. R = (25+5x)(200-x) O C. R = (25+x)(200-15x) O d. R = (25+5x)(200-15x)
