Answer:
y intercept
Step-by-step explanation:
At first I didn't think there was enough information, but there is. In general terms, for any polynomial which is also a function, making x = 0 gives the point where (0,b) = the y intercept.
For example
using f(x) = x^2 + 4x + 6 when x = 0 the result left is f(0) = 6 so the y intercept is (0,6)
If you have x^2 + 6x the y intercept is (0,0)
