What is the vertex of the parabola?

(-1, 0)
(0, -3)
(1, -4)
(3, 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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
