Answer:
y = 1/3(x -8)(x +2)
Step-by-step explanation:
When the function has x-intercept p, it has a factor (x -p). The two x-intercepts mean we can write the factored form as ...
y = a(x -8)(x +2)
Using the given point, we can find the value of 'a'.
-8 = a(4 -8)(4 +2) = -24a
a = -8/-24 = 1/3
In intercept form, the function is ...
y = 1/3(x -8)(x +2)
