Answer:
C
Step-by-step explanation:
So we have the function:
To find the inverse, switch h(x) and x, change h(x) to h⁻¹(x), and solve for it. Thus: "
So, take the natural log (log to base e) of both sides:
The right side will cancel:
Divide both sides by 2:
And we're done!
Our answer is C

Answer:
Therefore the equation of the line through ( -2 , -7 ) and ( 5 , 7 ) is
2x - y = 3
Step-by-step explanation:
Given:
Slope = 2 = m ( say )
Let,
point A( x₁ , y₁) ≡ ( -2 , -7 )
point B( x₂ , y₂) ≡ ( 5 , 7 )
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula,
Or
Equation of a line passing through a points A( x₁ , y₁) and i having slope m is given by the formula,
Substituting the given values in a above equation we get
Therefore the equation of the line through ( -2 , -7 ) and ( 5 , 7 ) is
2x - y = 3
