Basically, from what i can see and understand, is that you take the original price. lets use the chair.
$139.99 you choose which discount you would like to use either the $20 off or 20% off.
if you choose $20 then
$139.99-$20=119.99
but if you choose 20%
$139.99x0.20=27.99 (meaning you deduct $27.99 from $139.99)
139.99-27.99=$112
now you decide which one you'd choose. i would say 20% off because it costs less.

Given the functions f(x) = 3x and g(x) = x² + 1, find [(gºf)(x)]- [(fºg)(x)].

Ipatiy [6.2K]

Answer:

6x^2 - 2

Step-by-step explanation:

plug in f(x) into the g(x) formula given

g(f(x)) = (3x)^2 + 1

simplify

= 9x^2+2

plug in g(x) into the f(x) formula given

f(g(x)) = 3(x^2+1)

distribute

= 3x^2 +3

set g(f(x)) - f(g(x))

(9x^2+2) - (3x^2+3)

carry the negative

9x^2+2-3x^2-3

simplify by combining like terms

6x^2-2
