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

Identify the a, b and c values for this equation:
3x² - 8x + 15 = 0

• a=3, b=8, c=0

• a=3, b=-8, c=15

• a=3, b=8, c=15

Convert x²-6x+9 to factored form and identify the solution.

• (x-3)(x-3); x=3

• (x+3)(x+3); x=-3

• (x+4)(x+2); x=-4, -2

• Not factorable

Describe the role of 'c' in determining the position of a quadratic function on the graph.

• The role of 'c' is to determine the concavity of the graph

• The 'c' value represents the x-intercept of the quadratic function

• The role of 'c' in determining the position of a quadratic function on the graph is to represent the y-intercept.

• The 'c' value has no impact on the position of the quadratic function on the graph
