Question

write a polynomial in terms of h for the average velocity from t=1 to the time h seconds later (h cannot equal 0)?? s(t)=20-5t^2

Answer 1

f(x+h) - f(x)
----------
h

Answer 2

replace t by the values in the (..) and simplify as needed

Answer 3

then change x back to t :)

Answer 4

haha umm okay..so f(20-5t^2+h)-f(20-5t^2)/h??

Answer 5

no; not f(something else); f(x+h) - f(x)

Answer 6

f(♫) means that you replace the variable by ♫

f(♥) means that you replace the variable by ♥

f(x+h) means that you replace the variable by "x+h"

Answer 7

and i prolly should be consistent to the problem ....

Answer 8

s(x+h)-s(x) (20-5(x+h)^2) - (20-5(x))
--------- = ----------------------
h h

Answer 9

ohhhh i see gotchya

Answer 10

just in the end, x = t; so replace all your xs by ts
