Answer:
-2.34
Step-by-step explanation:
It is further away from 0
Answer: No. You reversed the domain and range
#2) B) x ≥ 0
#3) B) [0, ∞)
<u>Step-by-step explanation:</u>
#2 is asking about the domain, which is all of the x-values.
The graph appears to be touching the y-axis so it equals 0 and all other x-values are greater than zero. (0, 1), (1, 0), (2, -0.8), (3, -1.5), etc. All of the x-values are moving toward the right, which is positive infinity. --> x ≥ 0
#3 is asking for the range, which is all of the y-values.
The vertex is at (0, 0) and all other y-values are above zero (positive numbers), moving toward positive infinity. --> [0, ∞)

PEMDAS
Parenthesis, Exponents, Multiplication, Division, Adition, Subtraction.
3 + 27 ÷ ( 4 + 5 )
Do the parenthesis first ( 4 + 5 )
3 + 27 ÷ 9
Do the division next ( 27 ÷ 9)
3 + 3
Now addition.....( 3 + 3)

In order to find the sum between these 2 fractions, we need to find a common denominator, and in this case, it can be 15...


Now that we have a common denominator, we can add them up...

is ur answer.
Hope this helped!
