Let's first work out the pattern. Since it's an geometric progression, we can find the sum to n terms of the pattern.

$S_n = \frac{a(r^n - 1)}{r - 1}$
$S_n = \frac{9((-2)^n - 1)}{-3}$
S_n = -3((-2)^n - 1)

Now that we've developed our geometric progression, we can start to add sigma notation.

k
∑(-3[(-2)^n - 1])
n = 1

Plz mark me as brainliest if this helped :)
Graph the function. f(x) = 5/9 (x + 9) (x + 3)
