Question 977341: Question is:
Use the intermediate value theorem to show that the polynomial function has a zero in the given interval
f(x)=16x^4-7x^2+8x-1; [-3,0]
enter the value of f(-3)

f%28-3%29=1208
f%280%29=-1
So the function crosses the x axis in the interval (-3,0) so there must be a zero in the interval.
