Answer:

  f³(x) = 64/x⁶

Step-by-step explanation:

  f³(x) = (f(x))³ = (4/x²)³ = 4³/(x²)³

  f³(x) = 64/x⁶

_____

The applicable rules of exponents are ...

  (a/b)^c = (a^c)/(b^c)

  (a^b)^c = a^(bc)

Identify the zeros of f(x)=(x-7)(x+4)(3x-2)
alexgriva [62]

To find the zero you must set each factor equal to zero and solve for for x like so...

Factor (x - 7)

x - 7 = 0

x = 7

Factor (x + 4)

x + 4 = 0

x = -4

Factor (3x - 2)

3x - 2 = 0

3x = 2

x = \frac{2}{3}

All the zeros are:

-4, \frac{2}{3}, 7

Hope this helped!

PLS HELP! 7x +10y= -23<br><br> 7x + 6y = - 39
mote1985 [20]
4y = -23 + 39
4y = 16
y = 4

Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9

x = -9
y = 4
