y-intercept of a function is obtained by putting x = 0.
Therefore, y-intercept = (0 - 6) × (0 - 2) = 12
Therefore, y-intercept = (0 - 6) × (0 - 2) = 12

f(x) = (x – 6)(x – 2)
y-intercept occurs when x = 0
When x = 0
f(x) = (x – 6)(x – 2)
f(0) = (0 - 6) (0 - 2)
f(0) = (-6)(-2)
f(0) = 12
Answer: y-intercept = (0, 12)

Additional notes: To find x-intercept
f(x) = (x – 6)(x – 2)
x-intercept occurs when f(x) = 0
(x – 6)(x – 2) = 0
x - 6 = 0 or x = 2
x = 6 or x = 2
The x-intercept are : (6, 0) and (2, 0)
