Homework Statement
Find a polynomial f(x) of degree 4 which increases in the intervals (-∞,1) and (2,3) and decreases in the interval (1,2) and (3,∞) and satisifes the condition f(0)=1
Homework Equations
The Attempt at a Solution
Let f(x)=ax^4+bx^3+cx^2+dx+1
f'(1)=f'(2)=f'(3)=0
But using the above results I get only 3 eqns whereas there are 4 variables.
