If f(x) = 3х2 +1 and g(x) = 1-х, what is the value of (f-g)(2)?

(f - g)(2) = 13 - (-1) = 14

Step-by-step explanation:

Please write f(x) = 3х2 +1  as  f(x) = 3х^2 +1; use " ^ " to represent exponentiation.

We could either find the new function (f - g)(x) first and then substitute 2 for x, or we could evaluate both f and g at x = 2 and then subtract the results.

f(2) = 13 and g(2) = -1, so (f - g)(2) = 13 - (-1) = 14

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.

it is probably the graph on the bottom right.
