4. solve 2x + 8 = 0 by graphing the related function.
there are two solutions: + v8.
there are two solutions: 2 and -2.
f
o there are no real number solutions.
there is one solution: 2

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2

With finding limits of multi variable !

Can someone me with my math problems i have a bunch. i will give brainliest and lots of pleeeaaasssee
