Answer:
Option A is correct
\(h[j(5)] = -21\)
Step-by-step explanation:
Given the functions:
\(h(x) = x-1\) and
\(j(x) = -4x\)
Find the value of \(h[j(5)]\)
\(h[j(x)]\)
⇒\(h[-4x]\)
Replace x with -4x in h(x) we have;
\(h[j(x)] = -4x-1\)
Substitute x = 5 we have;
\(h[j(5)] = -4(5)-1\)
⇒\(h[j(5)] = -20-1=-21\)
Therefore, the value of \(h[j(5)]\) is, -21
