What is (f - g)(x)? f (x) = 24 – 22 + 9 9(2) = 23 + 3x2 + 12 (f - g)(x) =

(f - g)(x) = x^4 - x^3 - 4x^2 - 3

Step-by-step explanation:

Subtract  g(x)=x^3 + 3x^2 + 12 from f(x)= x^4 - x^2 + 9

First, take the negative of every term (including the label g(x) ) of g(x), obtaining  -g(x) = -x^3 - 3x^2 - 12.

Now combine this result with f(x):

 f(x)= x^4 - 0x^3 - x^2 + 9

-g(x) =       - 1x^3 - 3x^2 - 12

(f - g)(x) = x^4 - x^3 - 4x^2 - 3

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
