Answer:

B) f(x) = 2/5㏒(x) + 2

Step-by-step explanation:

Given graph

f(x) = ㏒₂ x

Changes

Transformed up by 2 units
vertically compressed by factor of 0.4

Solving

Shifted up by 2 units

f(x) = ㏒₂ (x) + 2

Vertically compressed by factor of 0.4

f(x) = 2/5㏒(x) + 2

8^x=2 8 to the power of x = 2. Find the value of x.

a_sh-v [17]

Answer:

$\huge{ \bold{ \boxed{ \sf{x = \frac{1}{3} }}}}$

☪ First , Let's know about Exponential Equation :

⤿ Let's take an equation : $\sf{ {2}^{x} = 8}$ .

In this equation , the variable ' x ' is the exponent of the base 2. Such an equation in which variable appears as an exponent of a base is known as exponential equation. The following axioms are useful while solving the exponential equations :

If $\sf{ {a}^{x} = {a}^{b} }$ , then $\sf{x = b}$
If $\sf{ {a}^{x} = 1}$ , then $\sf{ {a}^{x} = {a}^{0} }$ and x = 0

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

☯ Now , Let's Solve :

$\underline{ \sf{Given \: Exponential \: Equation \: : {8}^{x} = 2}}$

In this equation , the variable 'x' is the exponent of the base 8 .Write $\sf{ {8}^{x} }$ in exponential form with the base of 2

↦ $\sf{ {2}^{3x} = 2}$

Write the number 2 in exponential form with the base of 2.

↦ $\sf{ {2}^{3x} = {2}^{1}}$

Since the bases are same , cut 2 on both sides and set the exponents equal.

↦ $\sf{ { \cancel{2}} \: ^{3x} = { \cancel{2} } \: ^{1} }$

↦ $\sf{3x = 1}$

Divide both sides by 3

↦ $\sf{ \frac{3x}{3} = \frac{1}{3}}$

↦ $\boxed{ \bold{ \sf{x = \frac{1}{3} }}}$

And we're done!

Hope I helped!

Have a wonderful day! ツ

38 degrees 2x degrees +6 degrees

ratelena [41]

STEP
1
:
Pulling out like terms

Pull out like factors :

32 - 2x = -2 • (x - 16)

STEP
2
:

Equations which are never true:

2.1 Solve : -2 = 0

This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:

2.2 Solve : x-16 = 0

Add 16 to both sides of the equation :
x = 16
