Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (6, 5) and (x₂, y₂ ) = (- 3, 1)
d =
=
=
= ≈ 9.85 ( to 2 dec. places )
Solution:
Given expression is
To find the inverse of y.
⇒
Do cross multiplication.
⇒ y = –6 × 3
⇒ y = –18
Inverse of y means reverse the function.
We know that inverse of y is .
⇒
Hence, inverse of y is
