Question

Let f(x) = 9x - 2 and g(x) = -x + 3. Find f(g(x)).
a. -9x+27
b. -9x+25
c. -9x+5
d. -9x-2

can someone tell me how to solve this

Answer 1

we know g(x)=-x+3
then f(g(X))=f(-x+3)
then substitute the x value

Answer 2

@chorrigan15

Answer 3

so it would be b @sreekar369

Answer 4

u r \[correct\]

Answer 5

thank you

Answer 6

wait!! i think it's c @chorrigan15 @sreekar369

Answer 7

\[f(g(x))=(-(9x-2)+3)\]\[=-9x+2+3\]\[=?\]solve it @chorrigan15

Answer 8

u r wrong

Answer 9

why ?

Answer 10

g(x)=-x+3
f(g(x))=f(-x+3)
how will u substitute it tht reverse

Answer 11

f(g(x))=-(9x-2)+3

Answer 12

=>f(-x+3) tht means u shuld sub the value in f(x) value lol

Answer 13

Srry
Overlook
You're rite
@sreekar369
f(-x+3)
9(-x+3)-2
-9x+27-2
-9x+5

Answer 14

-9x+25*

Answer 15

ok ok
