Answer: 1st, 3rd, and 4th functions
Step-by-step explanation:
Assuming k(x)=9x^2, all the other functions have inverses because they are linear, meaning they must be one-to-one.
Answer:
u = ± 4
Given
u² = 16 ( take the square root of both sides )
u = ± = ± 4
u = - 4, u = 4
The answer should be true
1/2^4
n=9
because 3 times 9 =27 plus 17 =44
