The functions r and s are defined as follows.

irina1246 [14]

Answer:

r(s(-2)) = -2

Step-by-step explanation:

We are given these following functions:

$r(x) = -2x + 2$

$s(x) = x^2 - 2$

Find the value of r(s (-2)).

First we find the composition of r and s functions. It is:

$r(s(x)) = r(x^2-2) = -2(x^2-2) + 2 = -2x^2 + 6$

At x = -2

$r(s(-2)) = -2(-2)^2 + 6 = -8 + 6 = -2$

r(s(-2)) = -2

mihalych1998 [28]

Answer:

20078/243

Step-by-step explanation:

sn = a1-a1r^n/1-r

sn = a1 * 1-r^n/1-r

s7 = 6 * 1 - (-5/3)^7/1-(-5/3)

s7 = 6 * 10039/729

s7 = 6 * 10039/243*3

s7 = 2 * 10039/243

s7 = 20078/243
