Question

1. determine the average rate of change of $f(x)=x^2 + 4x - 5$ on the interval $1, 3$

$a,b$
$f(1) =$
$\frac{f(b)-f(a)}{b-a}$ $a,b$
multiple-choice question
what are the x-values in the interval?
select all the answers.
$b = 3$
$b = 1$
$a = 3$
$a = 1$

Explanation:

The interval given is [1, 3], which follows the form [a, b] where a is the left (lower) x-value and b is the right (upper) x-value.

Answer:

a = 1, b = 3
