The f⁻¹ means that you have to find the inverse of the given original function. The solution is shown below. First, interchange the x and y variables, then solve for y. 

f(x) = ∛(x - 2) + 8
y = ∛(x - 2) + 8
x = ∛(y - 2) + 8
x - 8 = ∛(y - 2)
[x - 8 = ∛(y - 2)]³
(x - 8)³ = y - 2
y = (x - 8)³ + 2
f⁻¹(x) = (x - 8)³ + 2

The answer is A.

PLEASE HELP ! Find the zeros of the given function.
photoshop1234 [79]

Answer:

-1, 4+i, 4-i

Step-by-step explanation:

x^4- 6x^3 + 2x^2 + 26x + 17

Using the rational root theorem

we see if 1, -1, -17 or 17 are roots

Check and see if 1 is a root

1^4- 6(1^3) + 2(1^2) + 26(1) + 17=0

1-6+2+26+17 does not equal 0  1 is not a root

-1

1^4- 6(-1^3) + 2(1^2) + 26(-1) + 17=0

1 +6 +2 -26+17 = 0

-1 is a root

Factor out (x+1)

(x+1) ( x^3-7x^2+9x+17)

Using the rational root theorem again on x^3-7x^2+9x+17

Checking -1

-1 -7 -9 +17=0

-1 is a root

(x+1) (x+1) (x^2-8x+17)

Using the quadratic on the last

8 ±sqrt(8^2 - 4(1)17)

--------------------------------

    2

gives imaginary roots

A car is traveling at a steady speed. It travels 2 1/2
Ksivusya [100]

Answer:

It will travel

33 \frac{1}{4}  \: miles

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes}  =  \frac{x}{45 \: minutes} \\  \\  \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} }  =   \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} }    \\  \\  x = 33\frac{3}{4}
