Answer:
25x^2 -1
Step-by-step explanation:
If you multiply parentheses:
(5x*5x) + (5x*-1) + (1*5x) + (1*-1)
25x^2 - 5x + 5x -1
25x^2 -1
A simpler way is to memorize this formula
(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)
Answer:
both domain and range are {-4, -3, -2, -1, 0, 1, 2, 3, 4}
it <u>IS a function</u>
Step-by-step explanation:
The domain is the list of x-values of the plotted points. It is all the integers from -4 to +4, inclusive.
The range is the list of y-values of the plotted points. It is all the integers from -4 to +4, inclusive. (domain and range are the same for this function)
No x-value has more than one y-value associated with it, so this relation IS A FUNCTION.
