If f(x) = 2x + 1, and
g(x) = x - 3, then
f(g(x)) = [ ? ]x + [ ]

First box +2

Second box -5

Step-by-step explanation:

Just an Example,

If f(x) = 2x + 1  and we need f(2) we would replace the x in the function with the number 2 because 2 is the domain of the function , so f(2) would become,

f(2) = 2(2) + 1

f(2) = 4 + 1 = 5

Now the question is what is f(g(x)) in this case the domain of the function is g(x). In simpler words we replace x with the function g(x) so here goes,

so,

f(g(x)) = 2x - 5

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest
