Question

Use the Intermediate Value Theorem to show there is a zero in [-3,-2] for the polynomial function f(x)=3x^3-10x+9

Answer 1

find \(f(-3)\) and then find \(f(-2)\)
one will be positive,one negative (i have no idea which )

Answer 2

then argue that since \(0\) is between the positive value and the negative value, since the function is continuous it must be zero somewhere in there

Answer 3

hey will you help me with another question?
