Answer:
Inverse of f(x)=-x^3-9 is ![f^{-1}(x)=\sqrt[3]{-x-9}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7B-x-9%7D)
Option B is correct option.
Step-by-step explanation:
We need to find inverse of 
For finding the inverse replace f(x) with y
Now, solve for x
Adding 9 on both sides
Multiply both sides by -1
Taking cube root on both sides:
![x^3=-y-9\\\sqrt[3]{x^3} =\sqrt[3]{-y-9} \\x=\sqrt[3]{-y-9}](https://tex.z-dn.net/?f=x%5E3%3D-y-9%5C%5C%5Csqrt%5B3%5D%7Bx%5E3%7D%20%3D%5Csqrt%5B3%5D%7B-y-9%7D%20%5C%5Cx%3D%5Csqrt%5B3%5D%7B-y-9%7D)
Now replace x with f^{-1}(x) and y with x
So, inverse of f(x)=-x^3-9 is
Option B is correct option.
Answer:
Step-by-step explanation:
2x-6=3-x
+x on both sides
3x-6=3
+6 on both sides
3x=9
/3 on each side
x=3
I got D for the answer ...
Answer:
yes I can help you. the answer to the problem is 4/35.
Step-by-step explanation:
1. convert any mixed number into fractions.
your equation becomes 4/7÷5/1. this equals 4×1 over 7×5. multiply normally and your result is 4/35
Answer:the 24 for 1.19 is the better deal
