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

Which of the following equations represents a quadratic function?

•  $y=3+2x^2$  

•  $x=2y^2+3$  
  

•  $y=3x-2^2$  
  

•  $y=2^x-3$
