Question

If f(x) = 2x 2 - 3x + 1, find f(3) - f(2).

Answer 1

well plug in the values for x and then solve

Answer 2

ok

Answer 3

eg. f(3)=2(3) 2 - 3(3) +1
that gives you a hint to solve the other

Answer 4

first find f(3) by putting 3 in place of x this will be ur f(3)
then put x =2 this wil give u f(2).. then subtract the both will give u your answer [f(3) - f(2)]
