F(x) = 7x3 + 2x + 4; -1 and 0 use the intermediate value theorem for polynomials to show that the polynomial function has a real zero between the numbers given

Step-by-step explanation:

F(-1) = -5

F(0) = 4

Since F(x) is continuous, it cannot get from -5 to 4 without passing through zero somewhere in the interval x∈(-1,0)

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

just keep asking questions until you have a better understanding.
