Which one is NOT a form of quadratic functions?

• Standard Form
• Factored Form
• Regular Form
• Vertex Form

Convert the equation y= x²-8x+11 into vertex form.

• y= (x+4)²+5

• y= (x+4)²-5

• y=(x-4)²-5

• y= (x-8)²-53

Convert
 f(x) = 3(x - 5)² - 1 
to standard form.

• f(x) = 3x² -30x + 74
• f(x) = 3x² -10x + 24
• f(x) = 3x² -30x + 24
• f(x) = 3x² -30x + 75
