Use the intermediate value theorem to show that f(x) has a zero in the given interval. Please show all of your work. f(x)=2x^5-7x^3-4x^2+3; [0.6, 0.7]

Question

anonymous · Answer

replace x by 0.6 and by 0.7
one value will be postive, the other negative
conclude that since this function is continuous it must take on every value in between the postive and negative one, and so is zero somewhere

anonymous · Answer

Is this the answer?

anonymous · Answer

it is once you evaluate the function at 0.6 and at 0.7

anonymous · Answer

Well I need the answer because this work is due tonight & I don't know how to do it.

anonymous · Answer

replace x by 0.6 and use a calculator 
repeat with 0.7
