Answer:
Option 4 - \(h[j(2)]=-23\)
Step-by-step explanation:
Given : If \(h(x)=5x-3\) and \(j(x)=-2x\)
To find : Solve h[j(2)] ?
Solution :
First we find h[j(x)],
\(h[j(x)]=h[-2x]\)
\(h[j(x)]=5(-2x)-3\)
\(h[j(x)]=-10x-3\)
Now substitute x=2,
\(h[j(2)]=-10(2)-3\)
\(h[j(2)]=-20-3\)
\(h[j(2)]=-23\)
Therefore, Option 4 is correct.
