What is the name for a graph of a quadratic function?

• vertex

• line

• parabola

• axis of symmetry

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
