For the given functions f and g, find the requested composite function value.
f(x) = x - 8
x , g(x) = x2 + 6; Find ( g H f)(-2).


Sagot :

Answer:

106

Step-by-step explanation:

Composite function:

A composite function is represented by:

[tex](g \circ f)(x) = g(f(x))[/tex]

In this question:

[tex]f(x) = x - 8[/tex]

[tex]g(x) = x^2 + 6[/tex]

[tex](g \circ f)(x) = g(f(x)) = g(x-8) = (x-8)^2 + 6[/tex]

Find ( gof)(-2).

When x = -2. So

[tex](g \circ f)(-2) = (-2-8)^2 + 6 = (-10)^2 + 6 = 100 + 6 = 106[/tex]

The answer is 106.
