Question

What are the x– and y–intercepts of the quadratic equation y = 2x2 – 8x + 6?

Answer 1

plug in x=0 and y=0

Answer 2

The constant in a polynomial function is always the y-int: (0,6)

Answer 3

6 is the y intercept and 1,3 are the x intercepts

Answer 4

Let y=0 and solve for x. Divide by 2 and factor.\[(x-3)(x-1)=0\]thus the x-ints are (3,0) and (1,0)
