Answer:
-infinity, infinity
Step-by-step explanation:
Domain is x, and in a quadratic equation like this one the x axis goes on forever. So the first answer of -infinity, infinity is correct.
(-inf, inf)
Remember, the domain of the function looks at purely the input values (x-axis), not your output values (y-axis).
Keeping this in mind, you can see that the x values stretch from the far left, -inf to the far right +inf.
Remember, as infinities aren't considered actual values, you put them in parentheses. This means your answer is (-inf, inf).
w-(-3)=7
Pretend that there is a -1 in front of the bracket
w-1(-3)=7
Mutiply the bracket by -1
(-1)(-3)=3
w+3=7
Move +3 to the other side. Sign changes from +3 to -3.
w+3-3=7-3
w=4
Answer: w=4
Answer: Polynomial
Answer x/3 -(-2)= 16
X/3+ 2=16
X/3=16-2
X/3=14
X= 14x3=42
Here ya go! Hope this helps!! :D
