Answer:
domain: (-∞,∞)
range: (-∞,∞)
Step-by-step explanation:
You need to convert this into a linear equation (y=mx+b)
So we add 2y and divide by 2 to get y by itself
that gives us 5x-2=y
If you pictures this graph in your head you'll see that the domain and range are all real numbers
C
1.24
x = ± 3√6
2x² - 6 = x² + 48 ( subtract x² from both sides )
x² - 6 = 48 ( add 6 to both sides )
x² = 54 ( take the square root of both sides )
x = ± √54 = ± 3√6
