Answer:

The correct option is;

a. 0

Step-by-step explanation:

The given parameters are;

f(x) = x² - 1

g(x)  = √x

When carrying out operations in composite functions, we proceed as follows

[tex](f \circ g)(x) = f(g(x)) = f(\sqrt{x} ) = (\sqrt{x} )^2 -1 1 = x - 1[/tex]

Therefore, we have;

[tex](f \circ g)(1) = f(g(1)) = f(\sqrt{1} ) = (\sqrt{1} )^2 -1 1 = 1 - 1 = 0[/tex]

Therefore;

[tex](f \circ g)(1) = 0[/tex]
