Answer

B

Work Step by Step

We know that quadratic functions follow the form $y=ax^2+bx+c$. We see that the axis of symmetry of the given function must be: $$-\frac{b}{2a} =-\frac{-2}{.5(2)} =2$$ Since c is 3, we see that the only function with an axis of symmetry of 2 and a y-intercept of 3 is option B.
