If f (x) = 1/9x - 2, what is f-¹(x)? Help me pls?!?!?!?!??!?!?!?!? f-¹(x)= 9x + 18
f-¹(x)= 1/9x + 2
f-¹(x)= 9x + 2
f-¹(x)= -2x + 1/9

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

thus, the first answer choice, y = sec x, is the correct one
