Answer:
The correct answer is C.
Step-by-step explanation:
The given equation is;

This implies that;


Let us write in Cartesian coordinates by substituting;



Square both sides;

This implies that;



This is an equation of a parabola that opens upwards with a y-intercept of
.
The correct choice is C
Answer:
a
Step-by-step explanation:
we know that
If the only factors a polynomial are
and itself, then that polynomial is prime.
so
If the polynomial has at least one root (one x-intercept) then the polynomial is not prime
Using a graph tool
<u>case 1) </u>

see the attached figure N 1
The polynomial has one root-------> the polynomial is not prime
<u>case 2) </u>

see the attached figure N 2
The polynomial has three roots-------> the polynomial is not prime
<u>case 3) </u>


see the attached figure N 3
The polynomial has zero roots-------> the polynomial is prime
<u>case 4)</u>


see the attached figure N 4
The polynomial has two roots-------> the polynomial is not prime
therefore
<u>the answer is</u>
------> is prime
