Question

Write the equation of the function if its rate of change is -14 and its intial value is 14

Answer 1

Answer:

$f(x) = -14x + 14$

Step-by-step explanation:

Given

$Initial\ Value = 14$

$Rate = -14$

Required:

Write as a function

Let x be the quantity that changes:

A function is of the form:

$f(x) = mx + b$

Where

m = slope or rate

b = y intercept or initial value.

So, we can say that:

$m = -14$

$b = 14$

Substitute values for b and m in $f(x) = mx + b$

$f(x) = -14x + 14$
