2 3 x - 6
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=3x2+9 f - 1 ( x ) = 3 x 2 + 9 is the inverse of f(x)=23x−6 f ( x ) = 2 3 x - 6
pls brain
Sometimes it helps to draw it out...

21
therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
slope m = - 2 → B
calculate m using the ' gradient formula '
m = (y₂ - y₁)/(x₂ - x₁)
choosing 2 'clear ' coordinates from the graph of the line
(x₁, y₁) = (0, 7) and (x₂, y₂) = (7, - 5
) =
= - 2
m =
Answer:
x ≠-8 x ≠ -2
Step-by-step explanation:
We cannot divide by zero, so the denominator cannot equal zero
X^2+6x-16≠0
Factor
(x+8) (x-2) ≠0
Using the zero product property
(x+8) ≠0 (x-2) ≠0
x ≠-8 x ≠ -2
