Answer:
Step-by-step explanation:
Given that s(x)= 2-x^2 and t(x)=3×
To find which value is equivalent to ( s(t(×)) (-7)
This is composition of functions where t is performed first and then s
x=-7
t(-7)=[tex]3^{-7}[/tex]
NOw s(t(-7))=s([tex]3^{-7}[/tex])
=[tex]2-(3^{-7})^{2} =2-\frac{1}{3^{14} }[/tex]
simplify to get
1.99999
