Answer:
[r - 7][r + 7]
Step-by-step explanation:
Whenever you have a negative perfect square in the trinomial, like this one, that will tell you that you have to multiply conjugates, which are two monomials with <em>additive</em> <em>inverses</em><em> </em>inside. Additive inverses ALWAYS result in zero, which is your <em>B</em><em>.</em>

Answer:
{3, 6}
Step-by-step explanation:
f(x) is the same thing as y. f(x) or y are the values that are shown in the range.
The domain represents all possible values of x. Data must be in an (x, y) form, where any value of "y" would need a partner, "x".
Substitute all of the possible x-values into the formula to find all possible y-values (the range).
f(x) = x² - 2x + 3
f(-1) = (-1)² - 2(-1) + 3
f(-1) = 1 + 2 + 3
f(-1) = 6
f(x) = x² - 2x + 3
f(0) = (0)² - 2(0) + 3
f(0) = 0 - 0 + 3
f(0) = 3
f(x) = x² - 2x + 3
f(2) = (2)² - 2(2) + 3
f(2) = 4 - 4 + 3
f(2) = 3 Do not write repeated numbers
The possible y-values are 3 and 6.
Writ the range in set notation in the brackets {}. Order the numbers from least to greatest.
Range is {3, 6}.
