This is last question and i wanna go to bed

what is (f−g)(x)?

f(x)=x^4−x^2+9

g(x)=x^3+3x^2+12

enter your answer.

(f−g)(x)=

x^4 -x^3 -4x^2-3

Step-by-step explanation:

f(x)=x^4−x^2+9  

g(x)=x^3+3x^2+12

(f−g)(x)= x^4−x^2+9 - (x^3+3x^2+12)

 Distribute the minus sign

(f−g)(x)= x^4−x^2+9 - x^3-3x^2-12

I like to line them up vertically

x^4        −x^2+9

    - x^3 -3x^2-12

x^4 -x^3 -4x^2-3

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

answer: 193

explanation:

200-7 = 193
