Question

Can the intermediate-value theorem be used to show there is a solution the equation f (x) = 0 on the interval [1, 2]? Give an explanation why.
f(x) = 3x^3- sqrt(2x+2)

Answer 1

) Yes, because f (1) > 0 and f (2) < 0.
b) Yes, because f (1) < 0 and f (2) > 0.
c) No. because f (1) < 0 and f (2) < 0.
d) No, because f (1) > 0 and f (2) > 0.

Answer 2

once again we check the endpoint. maybe in our heads

Answer 9

I got d for this

Answer 10

cause both are positive >0

Answer 11

\[3-\sqrt{4}=1\]

Answer 12

and the next one is obviously positive. fine

Answer 13

these are pretty straight forward yes?
