Find the inverse of the function.<br> y= √x - 4

EastWind [94]

Answer:

The inverse is $f^{-1}$ (x) = $(x+4)^{2}$

Step-by-step explanation:

(By the way, $f^{-1}$ (x) is f negative one of x, like f(x), but inverse)

f(x) = $\sqrt{x}$ - 4 is the same as y = $\sqrt{x}$ - 4

y = $\sqrt{x}$ - 4 start with the equation.

x = $\sqrt{y}$ - 4 switch x and y.

x + 4 = $\sqrt{y}$ add 4 to both sides.

$(x+4)^{2}$ = y square both sides.

$f^{-1}$ (x) = $(x+4)^{2}$ change y to the inverse f(x) format.

I hope this helps! :)

Answer:

Multiplying Integers

1) (-4)(-12) = 48

2) -8 X (-8) = 64

3) (-8)(-10) = 89

4) 5 x 1 = 5

5) (-10)(11) = -110

6) (-3)(-8) = 24

9) 4 x (-10) = -40

7) -2 x 6 = -12

8) 7(-12) = -84

10) (-9)(-6)(2) = 108

11) (-10)(-7)(-4) = -280
