Question

Can y’all help this is for Plato !!!!!! PLEASEEE HELP ME

Answer 1

The two real values that are not in the domain of the composition are x = 2 and x = -2.

What two numbers are not in the domain of f°g?

Here we have:

f(x) = 1/x

g(x) = x^2 - 4

The composition is:

f°g = f(g(x)) = 1/(x^2 - 4)

The two values that are not in the domain are the values of x such that g(x) = 0, because we can't divide by zero.

g(x) = 0 = x^2 - 4

4 = x^2

±√4 = x

±2 = x

So g(x) = 0 when x = 2 or x = -2, so these are the two real values that are not in the domain of f°g.
