Question

Use intermediate value theorem to show that the polynomial function has a zero in the given interval.
f(x)=9x^4-3x^2+5x-1; [-3,0]
f(-3)=
value of 0=

anonymous · Answer

find $f(-3)$ and $f(0)$
one will be positive, the other negative
then since 0 is between the two values, the function must be zero in that interval

anonymous · Answer

So how would I find f(-3)? @satellite73
