Question

If s(x)=2-2x^2 and t(x)=3x, which value is equivalent to (s•t)(-7)?

Answer 1

Answer:

Step-by-step explanation:

Answers

-439

(s o t)(x)=s(t(x))

(s o t)(-7)=s(t(-7))

x=-7→t(-7)=3(-7)→t(-7)=-21

(s o t)(-7)=s(t(-7))=s(-21)

x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439

(s o t)(-7)=s(t(-7))=s(-21)=-439

Answer: Option A -439
