Question

plzz help will give medal!

Answer 1

@mathmate @AutoTune @BrainlyOfficial @Evoker plz help

Answer 2

f(x)=x-2
f(g(x))=g(x)-2
Now g(x)=x^2-7x-9
So f(g(x))=x^2-7x-9-2
Put x=-1 and simplify

Answer 3

@Visarika23 so what would be the final answer?

Answer 4

It should be -3

Answer 5

@Visarika23
Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)).

Let f(x) = 5x + 12. Find f−1(x).

Let f(x) = −4x + 7 and g(x) = 10x − 6. Find f(g(x)).

Answer 6

Do you know how to solve these?

Answer 7

no

Answer 8

@liziekay plz help

Answer 9

Basically, plug in f into g so x+8 x2-6x-7)

Answer 10

From @Visarika23's post:
`f(x)=x-2`
`f(g(x))=g(x)-2`
`Now g(x)=x^2-7x-9`
`So f(g(x))=x^2-7x-9-2`
`Put x=-1 and simplify`
The next step is to put x=-1 in the last line,
f(g(x))=(-1)^2-7(-1)-9-2
=.... (take out your calculator and figure it out).
