Given the function g(x) = x2 – 10x + 19, determine the average rate of change of
the function over the interval 3 < x < 6.

Respuesta :

Answer:

The average rate of change for g(x) on the interval 3 ≤ x ≤ 6 is -1.

Step-by-step explanation:

We want to find the average rate of change of the function:

[tex]g(x)=x^2-10x+19[/tex]

Over the interval:

[tex]3\leq x\leq 6[/tex]

The average rate of change is essentially the average slope of the function. So, we want to find the slope between g(3) and g(6).

Evaluate both points:

[tex]g(3)=(3)^2-10(3)+19=-2[/tex]

[tex]g(6)=(6)^2-10(6)+19=-5[/tex]

Thus, we obtain the two points (3, -2) and (6, -5).

The slope between them is:

[tex]\displaystyle m=\frac{(-5)-(-2)}{(6)-(3)}=\frac{-3}{3}=-1[/tex]

Therefore, the average rate of change for g(x) on the interval 3 ≤ x ≤ 6 is -1.
