Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x2−1 f - 1 ( x ) = x 2 - 1 is the inverse of f(x)=2x+2 f ( x ) = 2 x + 2 .
-6 it is just the opposite of the number. So a positive would be a negative and a negative a positive. So the answer to your question is -6.
D is also correct. if you need an explanation let me know
Answer:
10 or 4.
Step-by-step explanation:
[(x - 7)^2 + 6 - 13 ] * 4 - 1 = 7
(x^2 - 14x + 49 - 7) * 4 - 1 = 7
4x^2 - 56x + 196 - 28 - 1 - 7 = 0
4x^2 - 56x + 160 = 0
4(x^2 - 14x + 40) = 0
(x - 10)(x - 4) = 0
x = 10 , 4
