The point of intersection of the two functions is
on the line y = x; therefore, the functions are
inverses of each other.
Step-by-step explanation:
the answer to your question might be (B).
Answer:
-1 and -8
Step-by-step explanation:
x^2+2*9/2*x+(9/2)^2-(9/2)^2+8=0
(x+9/2)^2+32/4-81/4=0
(x+9/2)^2-49/4=0
(x+9/2)^2=(7/2)^2
so
x+9/2=7/2
x=7/2-9/2
x=-2/2
x=-1
or
x+9/2=-7/2
x=-7/2-9/2=-16/2
x=-8
