Answer:
45
Step-by-step explanation:
When you're completing the square you're adding (b/2)^2 which in this case is (-5)^2 or 25. This is because when you rewrite it as a square binomial you write it in the form (x+(b/2))^2 which is going to result in x^2+b+(b/2)^2. Since you need to reach 25 you need to add 45 since the last value is at -20.
That expression would be 6n-3, where n is the number in question.
Using a graphing tool, we can see that the whole range of the function
is <span>y</span><span> ∈ [0,∞)
Now, in the interval
</span>
{x | –8 < x < 8}.
The range is
y<span>
∈ [0 ; 6.708) </span>
No, he is not correct. 2^3 = 8 and 5^3 = 125, so 8•125 = 1,000. 10^9 = 1,000,000,000.
