Explanation:
Need to find h(g(5))
g(5) = 5^2 - 3
= 25 - 3 = 22
h(22) = 22x2 - 1
= 44 - 1 = 43

\(g(x) = x^2 - 3\)
=> \(g(5) = 5^2 - 3 = 25 - 3 = 22\)
=> \(h(x) = 2x - 1\)
=> \(h(g(5)) = h(22) = 2(22) - 1 = 44 - 1 = 43\)
Answer C
=> \(g(5) = 5^2 - 3 = 25 - 3 = 22\)
=> \(h(x) = 2x - 1\)
=> \(h(g(5)) = h(22) = 2(22) - 1 = 44 - 1 = 43\)
Answer C
