Question

which of the following function notations corresponds to the equation below?
$y - 6.37x = -3$
a. $f(x) = 6.37x - 3$
b. $f(x) = 3x - 6.37$
c. $f(y) = 6.37y - 3$
d. $f(y) = 3y - 6.37$

Explanation:

Step1: Isolate y in the equation

Add $6.37x$ to both sides.
$y - 6.37x + 6.37x = -3 + 6.37x$

Step2: Simplify to get y as f(x)

Rewrite $y$ as $f(x)$.
$f(x) = 6.37x - 3$

Answer:

A. $f(x) = 6.37x - 3$
