Answer:
Step-by-step explanation:Domain is the set of x values in which the function exists. Range is the set of y values in which the function exists. f(x) = 8 / (x + 9) Since the denominator cannot be zero, we set the denominator equal to zero.
Answer:
Step-by-step explanation:
If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.
16x^ = (4x)^2 . . . . a perfect square
49 = 7^2 . . . . . . . a perfect square
-2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...
16x^2 -56x +49 = (4x -7)^2
_____
The sign in the binomial factors is the same as the sign of the middle term of the trinomial.
