Jackie claims that points with the same xx- and yy-coordinates must lie in quadrant i or quadrant iii. do you agree or disagree? explain your answer.

True.

Step-by-step explanation:

This statement is true because if a point has the same x and y coordinates it means that they have the same sign, and the only quadrants where both coordinates have the same sign are Quadrant I and Quadrant III, since for Quadrant I both are positive and for Quadrant III both are negative. For the other Quadrants the x and y coordinates cannot be the same because their sign are necessarily different.

[2, 2.5)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)

(2.5, 3]

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
