0.50 because the 8 is in the hundredth place and is greater than 5 so you round it up. Then you turn that to a zero because the 8 becomes a 10 but you only use the zero. Then you turn the 4 to a 5 or else the number would be getting smaller and not larger.
Take a look at the horiz. line. It has arrows at both ends. That means that x goes on forever in both directions. Thus, the domain of this function is (-inf, +inf).
Answer:
- Both have 4 imaginary roots
Step-by-step explanation:
1)
1.
- x^2 + 9 = 0
- x^2 = - 9
- x = ± √-9
- x = ± 3i
2.
- x^2 + 6 = 0
- x^2 = -6
- x = ±√-6
- x = ± i√6
It has 4 imaginary roots and no real roots
2)
1.
- x^2 + 7 = 0
- x^2 = -7
- x = ± √7
- x = ± i√7
2.
- x^2 + 5 = 0
- x^2 = - 5
- x = ± √-5
- x = ± i√5
It has 4 imaginary roots and no real roots
