Question

the functions s and t are defined as follows.
s(x)=2x+2
t(x)=-2x² -2
find the value of s(t(3)).
s(t(3)) =

Explanation:

Step1: Calculate t(3) first

$t(3) = -2(3)^2 - 2 = -2(9) - 2 = -18 - 2 = -20$

Step2: Substitute t(3) into s(x)

$s(t(3)) = s(-20) = 2(-20) + 2 = -40 + 2 = -38$

Answer:

$-38$
