The x-intercepts of a function are found by setting y=0 and solving for x. In this case the function is in fully factored form, which means that we can find the x-intercepts by solving:

`0=(x+6)^2(x-2)^2` set each factor to zero

so the x-intercepts are x=-6 and x=2.

The y-intercept is found by setting x=0 and solving for y, which gives:

`y=(6)^2(-2)^2`

`=36(4)`

`=144`

The y-intercept is y=144.

For large values of x, the function resembles the polynomial of the highest degree.

If we expand out the function, we get:

`f(x)=(x+6)^2(x-2)^2`

`=x^4+` lower degree terms

**So for large values of x, the function resembles `y=x^4` . The x-intercepts are x=-6 and x=2. The y-intercept is y=144.**
