Answer:
The inverse of logarithmic function
f⁻¹(x)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given f(x) = log₂ˣ ( 2 is a radical)
<em>Let x₁ and x₂ be the ∈ domain f</em>
⇒f(x₁) = f(x₂)
⇒
⇒ x ₁ = x₂
<em>Therefore f(x) is one-one function</em>
Let y = f(x) = log₂ˣ
⇒ y = log₂ˣ
⇒
<em>f(x) is a one-one function and onto</em>
⇒
⇒ f⁻¹(x)
<em>The inverse of logarithmic function </em>
f⁻¹(x)

Answer:
-36
Step-by-step explanation:
13+k/3=1
k/3=-12
3(k/3)=(-12)3
k=-36
You can multiply 7.32 x 0.07= 0.5124
Round to $0.51
Or you can find 1% of $7.32 = 0.0732
So 7% would be 7 x 0.0732= $0.5124 Round to 51 cents
About 1/3 between 27 and 28
