Question

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

$f(1) = (1)^2 + 4(1) - 5 = 1+4-5=5-5=0$
$f(3)=3^2 + 4(3) - 5 = 9+12-5=9+7=16$
$\frac{f(b)-f(a)}{b-a}$ $a,b$
multiple-choice question
what are the y-values of the function? select two answers.
$y = 0$
$y = 1$
$y = 3$
$y = 16$

Explanation:

Step1: Calculate f(1)

$f(1) = (1)^2 + 4(1) - 5 = 1 + 4 - 5 = 0$

Step2: Calculate f(3)

$f(3) = (3)^2 + 4(3) - 5 = 9 + 12 - 5 = 16$

Step3: Identify y-values

The y-values are f(1) and f(3).

Answer:

y = 0
y = 16
