Find the factors of function f, and use them to complete this statement. f(x)=2x^(4)-x^(3)-18x^(2)+9x From left to right, function f has zeros at

Hello,

Zeros are : 0;  1/2; -3; 3.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
