What is the inverse of the function of (x)=2^(x)+6

Mathematics
1 answer:
Elden [556K]3 years ago
7 0

Answer:

Option D.

Step-by-step explanation:

To find the inversion of a function follow the following procedure

1) Replace x with y in the function and clear y

y=2^{(x)} + 6 ------>  x = 2^{(y)}+ 6

x-6 = 2^y

y = log_2(x-6)

2) Check. The range of f(x) is the domain of f^{-1}(x).

So if f(a) = b, this means that f^{-1}(b) = a.

f(2) = 2^2+ 6 = 10

f^{-1}(x) = log_2(10-6) = 2

Is fulfilled. Therefore y=log_2(x-6) is the inverse of f(x) = 2^{(x)} +6

For what power of q is its value 1?​
DedPeter [7]

Answer:

  0, for q ≠ 0 and q ≠ 1

Step-by-step explanation:

Assuming q ≠ 0, you want to find the value of x such that ...

  q^x = 1

This is solved using logarithms.

__

  x·log(q) = log(1) = 0

The zero product rule tells us this will have two solutions:

  x = 0

  log(q) = 0   ⇒   q = 1

If q is not 0 or 1, then its value is 1 when raised to the 0 power. If q is 1, then its value will be 1 when raised to <em>any</em> power.

_____

<em>Additional comment</em>

The applicable rule of logarithms is ...

  log(a^b) = b·log(a)

The results of dividing 1 into pieces that are each 1/9 of a whole is 9

<h3>Division of fraction</h3>

1 ÷ 1/9

  • multiply by the reciprocal of 1/9 which is 9/1

1 ÷ 1/9

= 1 × 9/1

= (1 × 9) / (1 × 1)

= 9/1

= 9
