Help me answer this question please

ANSWER

{f}^{ - 1}  =\pm \sqrt{x + 1}

EXPLANATION

The given function is

f(x) =  {x}^{2}  - 1

Let

y =  {x}^{2}  - 1

Interchange x and y to get:

x=  {y}^{2}  - 1

Solve for y,

x + 1 =  {y}^{2}

Take square root of both sides to get,

\pm \sqrt{x + 1}  = y

This is the same as:

y =  \pm \sqrt{x + 1}

Therefore the inverse is

{f}^{ - 1}  =\pm \sqrt{x + 1}

Pls help! What's the answer?
Ivan

Answer:

The answer is b = 8a

Step-by-step explanation:

As, 0 x 8 = 0

2 1/2 = 5/2, 5/2 x 8 = 20

5 x 8 = 40

7 1/2 = 15/2, 15/2 x 8 = 60

10 x 8 = 80

13 1/2 = 27/2, 27/2 x 8 = 108

So all variables "a" when multiplied by 8 will give us the value in "b"

So b = 8a
