I believe the correct answer is B. It is the polynomial x^2 – 9x – 18 that is a prime polynomial. Other options can be factored out to a number under the real number system while option B cannot give a whole number. The factors are as follows:
<span>A.) x2 – 7x – 18 9 and -2
B.) x2 – 9x – 18 10.68465844 and -1.684658438
C.)x2 + 3x – 18 3 and -6
D.)x2 + 17x – 18 1 and -18</span>
Answer:
9/40 or 0.225

Answer:
With
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Step-by-step explanation:
For this case we know the following function:
We can begin the zeros or the values where the function is 0 like this:
And solving for x we got:
Now we can rewrite the expression like this:
And we can find the position for the vertex at x with this formula:
With
And replacing we got:
And then with the coordinate of x for the vertex we can find the coordinate of y replacing the value of x obtained for the vertex.
Then we can find the intercept using the value of x=0 and replacing into the function we got:
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Problem
Method
A symmetric function is a function in several variable which remain unchanged for any permutation of the variables.
f(-x) = f(x)
