Which of the following is the inverse of y=3x?
shtirl [24]

Answer-

<em>The inverse of y=3^x is </em>

\boxed{\boxed{y=\log_3 x}}

<u>Solution-</u>

The given function is,

y=3^x

We can get the inverse by interchanging he variable x and y among themselves and then separating each variables.

So in the inverse would be,

\Rightarrow x=3^y

Taking log of both sides,

\Rightarrow \log x=\log 3^y

As,

\log a^b=b\times \log a

Applying the same,

\Rightarrow \log x=y\times \log 3

\Rightarrow y=\dfrac{\log x}{\log 3}

As,

\log_b a=\dfrac{\log a}{\log b}

Applying the same,

\Rightarrow y=\log_3 x

Therefore, the inverse of y=3^x is y=\log_3 x.

Answer:

abc = - 126

Step-by-step explanation:

(2x + 3)(3x - 1) ← expand product using FOIL

= 6x² + 7x - 3 ← in standard form

with a = 6, b = 7, c = - 3

Then

abc = 6 × 7 × (- 3) = - 126

No because when you variables (with exponents) you add the exponents together.
x^3 • x^3 • x^3 = x^(3+3+3) = x^9
Let’s plug in a number for x to make sure this is correct.
x = 2
2^3 • 2^3 • 2^3 = 8 • 8 • 8 = 512
2^9 = 512
