You didn't post any option, but the ration roots theorem states that all possible rational roots of a polynomial come in the form
where p divides the constant term and q divides the leading term of the polynomial. So, in your case, p divides 3 (i.e. it is 1 or 3), and q divides 5 (i.e. it is 1 or 5).
So, the possible roots are
For the record, this parabola has no real roots.
Answer:
Step-by-step explanation:
This is what it is as a mixed number
=
=
If you want it written in exponential form it would look like this:
Okay so in this question it says to solve f(7). This means to plug in the 7 every where you see an x, so that it looks like this: Then you'll solve it like a normal equation.
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!
