Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as g(x) is not properly written.

I'll assume the following:

[tex]f(x) = 3x^2 - 15[/tex]

[tex]g(x) = 1- 2x[/tex]

Required

Determine (f o g)(-6)

In functions:

(f o g)x = f(g(x))

So:

[tex](f o g)(-6) = f(g(-6))[/tex]

First, we calculate g(-6)

[tex]g(x) = 1- 2x[/tex]

[tex]g(-6) = 1 - 2*-6[/tex]

[tex]g(-6) = 13[/tex]

Substitute 13 for g(-6) in [tex](f o g)(-6) = f(g(-6))[/tex]

[tex](f o g)(-6) = f(13)[/tex]

Next, we calculate f(13)

[tex]f(x) = 3x^2 - 15[/tex]

[tex]f(13) = 3 * 13^2 - 15[/tex]

[tex]f(13) = 3 * 169 - 15[/tex]

[tex]f(13) = 492[/tex]

Hence:

[tex](f o g)(-6) = 492[/tex]
