a) determine values of a b and c
b) determine the calue of x that satisfies the conclusion of the Mean Value Theorem for f on the closed interval [0,3]
The first derivative is 3x^2+2ax+b
and the second is 6x+2a
so if you substitute 0=6(0)+2a
a= 0
also (0,-2) is a point so
-2=0+0+c
so c= -2
How would i find the rest of the information?
