Jan'ai was asked to determine the minimum for a function with zeros located at -1 and 5, which also has a y-intercept of (0,25). her work is shown. begin to write a function in factored form. f(x) = a(x+1)(x-5) substitute to determine a. -25 = a(0+1)(0-5) simplify and solve to find a. a=5 rewrite the function. f(x) = 5(x+1)(x-5) rewrite in standard form. f(x) = 5x^2-20x-25 find the x-coordinate of the vertex. x = -20/2(5) = -20/10; x = -2 find the y-coordinate of the vertex. y = 5x^2-20x-25 y = 5(-2)^2-20(-2)-25 y = 35 so (-2,35) which best describes the first error in jan'ai's work? a) she incorrectly determined the factors for the beginning function. b) she incorrectly determined the a value. c) she incorrectly transformed the equation to standard form. d) she incorrectly determined the x-coordinate of the vertex.
