any ideas?

which is greater than 0 so now i need to find a value where f(x)<0

i got a value of 1

hmmm ill go with -1 ?

is it 0 -1 or 1

hey yea that's wa i was plannin on doing but since its like ^72 i can't figure that part out

Hey i was jus wondering how to solve this equation i need to find a value of x when subsituted in the eqn is less than 0 so a negative value and a value of x when substituted into the eqn is greater than 0 so a positive value this will prove that a root exists between those domains (ie...
