Given the function f(x)= x^4-3x^3-2x^2+5x+1, use the intermediate value theorem to decide which of the following intervals contains at least one zero. select all that apply.
a) [-2,-1]
b) [-1,0]
c) [0,1]
d) [1,2]
e) [2,3]
f) [3,4]

Step-by-step explanation:

There are changes in the sign of the function value in the intervals listed above. Consequently, there must be a zero in the interval.

__

It is a 4th degree function and we have found locations for 4 zeros. There are no more, and none of these intervals has two zeros.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
