Answer:
The solutions are -3 and -6
Explanation:
First we would need to put the equation in standard form which is:
ax² + bx + c = 0
This can be done as follows:
x² + 18 = -9x
x² + 9x + 18 = 0
By comparison, we would find that:
a = 1
b = 9
c = 18
Now, to get the roots, we would use the quadratic formula shown in the attached image.
By substitution, we would find that:
either x =
or x =

Answer:
A.(-1,-1)
E.(4,64)
Step-by-step explanation:
We are given that
Function
We have to find all possible input-output pairs for the function.
Substitute x=-1
Then, the pair is (-1,-1)
Now, substitute x=-2
Then, pair is (-2,-8)
Now, substitute x=3
Now, substitute x=4
Now, substitute x=1
Then, y=1
Hence, Option A and E are true.
A.(-1,-1)
E.(4,64)
