What is the domain of the following parabola? u-shaped graph that opens up with a vertex of 2, negative 3 all real numbers x ≥ 1 x ≤ 2 y ≥ −3

Domain of the function that is parabola  is all real numbers.

Hence, option 1 is correct.

Step-by-step explanation:

We have been given a parabola opens up and with vertex (2,-3)

Then equation for the given parabola is:

Domain is the values of x from a function:

Hence, the domain can be any real number

Therefore, option 1 is correct that is all real numbers.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
