[tex]r(x) = -2x-2\\ s(x) = 2x^2+2[/tex]

[tex]s\big(r(2)\big) = s(-2\cdot 2-2) = s(-4-2) = s(-6) = 2\cdot(-6)^2+2 = 2\cdot 36+2 =\\ = 72+2 = 74[/tex]

[tex]\Rightarrow \boxed{s\big(r(2)\big) = 74}[/tex]

Answer:

  • 74

Step-by-step explanation:

Given functions:

  • r(x) = -2x - 2
  • s(x) = 2x² + 2

Find s(r(2)) in steps:

  • r(2) = -2*2 - 2 = - 4 - 2 = - 6
  • s(r(2)) = s(- 6) = 2(-6)² + 2 = 72 + 2 = 74
