Given that f(x)=x^2+1 and g(x)=x-4, find f(g(x)) answer choices are
a. f(g(x))=x^2-8x+17
b. f(g(x))=x^2+3
c. f(g(x))=x^2+x-3
d. f(g(x))=2x-7
I would apricate work to be shown since I have to in order to get credit.

d? maybe

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

b
