I think you would most likely add all of them well I think
I believe -4 hope this helped
For Domain<span>, you just need to watch out for Square Roots and/or Fractions! 1) a POLYNOMIAL (no square roots or fractions), i.e. f(x) = x^2 + 3x + 1, </span>domain<span> is "all real numbers." 2) a FRACTION (w/ no square root), i.e. f(x) = (2x+1)/(x^2+5x+6). Set bottom "not equal" to zero.</span>
In order to find the<u> roots</u> of the cubic equations by <u>graphing</u> you have to follow those steps
we have

we know that
The <u>roots</u> of the function are the values of x when the value of the function is equal to zero
Using a <u>graphing </u>tool
see the attached figure
The<u> roots</u> are

therefore
the answer is

Answer:
12x+16
3x-12
Step-by-step explanation:
