Given the function g(x) = x2 + 5x + 1, determine the average rate of change of
Elden [556K]

Answer:

-6

Step-by-step explanation:

The average rate of change of a function, f(x), on interval [a,b] is (f(b)-f(a))/(b-a).

So the avereage rate of change of a function, f(x)=x^2+5x+1, on [-9,-2] is

(f(-2)-f(-9))/(-2--9)

(f(-2)-f(-9))/(7)

Stop!

To find f(-2), you replace x in f(x) = x^2 + 5x + 1, with (-2) giving you f(-2)=(-2)^2+5(-2)+1=4-10+1=-6+1=-5.

To find f(-9), you replace x in f(x) = x^2 + 5x + 1, with (-9) giving you f(-2)=(-9)^2+5(-9)+1=81-45+1=36+1=37.

Continue!

(f(-2)-f(-9))/(7)

=(-5-37)/7

=(-42)/7

=-42/7

=-6

Jillian has $50 that she plans on investing in an account that will double her money every week. This can be represented by the
Arte-miy333 [17]
The part that would change would be the number 2.  It would become a 3 instead of the 2.  Tripling something means to have 3 groups of it.

The reason is that the $50 is not changing, nor would the number of weeks, x be changing.
