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

Question

amistre64 · Answer

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

amistre64 · Answer

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

amistre64 · Answer

then change x back to t :)

anonymous · Answer

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

amistre64 · Answer

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

amistre64 · Answer

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"

amistre64 · Answer

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

amistre64 · Answer

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

ohhhh i see gotchya

amistre64 · Answer

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