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.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
