I NEED HELP PLEASE, THANKS. :)

Hey there! :)

1st option.

Step-by-step explanation:

Begin by finding the vertex of the equation:

f(x) = |-x + 1|

f(x) = |-(x-1)|

The vertex of this graph is at (1, 0).

The only graph shown with an absolute value graph with

a vertex at (1, 0) is the 1st option.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

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

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

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
