use the intermediate value theoremto show that the polynomial function has a zero in the given interval
find the value of f (1.4)=
find the value of f (1.5)=
show work, thanks
A visit to the bottom of the page at
will allow you to enter your function and a list of values to evaluate.
Since you left out a + or - sign in 14x5, I'll not evaluate f(x), but you will surely find that f(1.4) and f(1.5) have opposite signs. So, the IVT says that there is a root in the interval.
