Cho 2 đường thẳng d1: 3x-y-3=0 và d2: x+y = 0. Phép đối xứng tâm I biến d1 thành d1': 3x-y+1 = 0 và biến d2 thành d2': x+y-6 = 0 là gì ?

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

there is no picture in order for this question to be answered

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
