Two different quadratic functions are described below: • Function A: This function has a vertex of (3, 2) and passes through the point (2, 3).
• Function B: This function is represented by the equation f (x) = (x - 1)(x - 5).
Which statement is true about these two quadratic functions?

A. Both functions have the same y-intercept.

B. Both functions have graphs that open upwards.

C. Function A and function B both have two real solutions.

D. The vertex of function A is lower on the graph than the vertex of function B.
