Which statements are true about the graph of the function f(x) = 6x -4

1.	Which statements are true about the graph of the function f(x) = 6x -4 + x2? (i) The vertex form of the function is f(x) = (x -2)2 + 2. (ii) The vertex of the function is (-3, -13). (iii) The axis of symmetry for the function is x = 3. (iv) The graph increases over the interval (-3, infinity). (v) The function does not cross the x-axis.
Answer» Which statements are true about the graph of the function f(x) = 6x -4 + x²? (i) The vertex form of the function is f(x) = (x -2)² + 2. (ii) The vertex of the function is (-3, -13). (iii) The axis of symmetry for the function is x = 3. (iv) The graph increases over the interval (-3, infinity). (v) The function does not cross the x-axis. Solution:
