Question

if f(x)=2x-3 & g(x)=x, What is f(g(2))

Answer 1

what will be g(2)=?

Answer 2

Just replace x with 2.

Answer 3

-2?

Answer 4

How come ? g(x)=x

Answer 5

so g(2)=

Answer 6

oh is it 0?

Answer 7

if,

g(x)=x

then

g(2)=2

Answer 8

\[f(g(x))=2g(x)-3=2*x-3=2x-3\]

Answer 9

Now just find f(2)or f(g(2)=?

Answer 10

\[f(g(2))=2*2-3=4-3\] put x=2

Answer 11

x cant equal 2 .

Answer 12

How can that be ?

Answer 13

we are supposed to find f(g(2)) which means value of f(g(x)) when x=2

Answer 14

my choices are -2,0,1,4

Answer 15

4-3=?
