for the graph of the quadratic function, identify the direction of the opening and the coordinates of the vertex. f(x)=(x+2)raised to the second -3

A: downward 2,3

B: upward -2,-3

C: downward -2,-3

D: upward 2,3

identify the equation of the a quadractic function with the vertex (0,1/4) that passes through the point (-1,17/4) and opens upward

A: f(x)= 4x raised to the second + 1/4

B: f(x)= -4x raissed to the second - 1/4

C: f(x)= 4x raised to the second - 1/4

D: f(x)= -4x raised to the second - 1/2
