Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

Step 2: Find Average

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$

Let F(x)=-7x-12 and g(x)=13-3x. What is f-g?

Oxana [17]

Answer:

$(f - g)x = -4x - 25$

Step-by-step explanation:

Given:

$f(x) = -7x - 12$

$g(x) = 13 - 3x$

Required:

$(f - g)x$

SOLUTION:

$(f - g)x = f(x) - g(x)$

$f(x) - g(x) = (-7x - 12) - (13 - 3x)$

$= -7x - 12 - 13 + 3x$

Collect like terms

$= -7x + 3x - 12 - 13$

$(f - g)x = -4x - 25$
