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:
<h2>
b) y = -3x - 7</h2>
Step-by-step explanation:
3x + y = 5 {subtract 3x from both sides}
y = -3x + 5 ← slope-intercept form
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = -3x + 5 ⇒ m₁ = -3 ⇒ m₂ = -3
(-1, -4) ⇒ x₁ = -1, y₁ = -4
The point-slope form:
y - (-4) = -3(x - (-1))
y + 4 = -3(x + 1)
y + 4 = -3x - 3 {subtact 4 from both sides}
