Let f(x) = -2x - 7 and g(x) = -4x + 3. Find (f o g)(-5)

A.
23

B.
3

C.
-9

D.
-53

Answer 2

ok wait

Answer 3

ok :p

Answer 4

we will compensation (-5) for each x at g(x) it will be
(-4(-5))+3= 23
then put 23 for each x at f(x) and it will be
(-2(23))-7=-53

Answer 5

get it :D ^_^ ?

Answer 6

yes thanks ^__^

Answer 7

ok :D wait again

Answer 8

ok :D

Answer 9

put (-7) for each x at g(x)
\[\frac{ (-7)+8 }{ (-7) }\]=\[\frac{ -1 }{ 7 }\]
then put (-1\7) for each x at f(x) it will be
\[(\frac{ -1 }{ 7 })^{2}+6\]=\[\frac{ 295 }{ 49 } or 6.020\]
