Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

The formula x = -b/2a is used to find

• the roots

• the x-value of the vertex

• the y-intercept

• the axis of symmetry

When a parabola opens downward the vertex is

• a minimum

• a maximum

• a vertex

• a parabola
