Consider the function f(x) = 4x2 + 5. find the value of f(x) when x = 2 and select the correct answer below. a. 13 b. 21 c. 69 d. 89

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
