Answer:

Step-by-step explanation:

Try to present the quadratic (polynomial) entirely in symbols:

p(x) = 4x^2 + 3x + 5

This polynomial's graph opens up, and its axis of symmetry is x = -b / (2a), or

x = -3 / 8.  Evaluating the polynomial at x = -3/8, we get y = 4.4375, so we know that the vertex is at (-3/8, 4.4375).

Next time kindly share the choices given you.
