Question

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







x–intercepts: (–3, 0) and (–1, 0)
y–intercept: (0, 6)








x–intercepts: (–3, 0) and (–1, 0)
y–intercept: (0, 3)








x–intercepts: (–3, 0) and (–1, 0)
y–intercept: (0, 3)








x–intercepts: (3, 0) and (1, 0)
y–intercept: (0, 6)

Answer 1

x-intercepts occur where y = 0.

0 = 2x² - 8x + 6
0 = 2(x² - 4x + 3)
0 = 2(x - 3)(x - 1)
x - 3 = 0 and x - 1 = 0
x = {3,1}
