Which of the following graphs represents a function

1 answer:

7 0

Where are the graphs? a function is when every input is paired with exactly one output(every x value must have exactly 1 y value). the vertical line test helps determine a function, a vertical line can’t intersect a graph at more then one point, if it does intersect in more then 1 point then it’s not a function

Square root 2x-1+2=5 what is x equal to?

KATRIN_1 [288]

Because your question isn't specific or formatted exactly, I cannot guarantee that my answer is what you expect.

√2x - 1 + 2 = 5
√(2x + 1)² = 5²
2x + 1 = 25
2x = 24
/2 /2
x = 12

Therefore x = 12.
Proof:

√2x - 1 + 2 = 5
√2(12) - 1 + 2 = 5
  √24 - 1 + 2 = 5
  √25 = 5
5 = 5
