Simonne has been following the stock ratings of Carter's Pork Bellies. She has noticed that the pattern can be modeled by a cosine function. During her observations, she has found the stock to have a maximum of x = 6, minimum of x = −2, and period of π. Which of the following cosine functions could model Simonne's stock rating?a. f(x) = 4 cos 2x − 4b. f(x) = 6 cos pi over 2 x + 2c. f(x) = 6 cos pi over 2 x − 4d. f(x) = 4 cos 2x + 2

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=5Rewrite the function. f(x) = 5(x+1)(x-5)Rewrite in standard form. f(x) = 5x^2-20x-25Find the x-coordinate of the vertex. x = -20/2(5) = -20/10; x = -2Find 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.
