Find the domain of the function. (enter your answer using interval notation.) f(x) = x + 6 if x ≤ −2 x2 if x > −2

1 answer:

6 0

The domain is the union of all of the "if" parts of the function definition. These are telling you where the function is defined, which is what the domain is.

... (-∞, -2] ∪ (-2, ∞) = (-∞, ∞)

Does anyone know this??

blagie [28]

Answer:

x = 38, y = 4

Step-by-step explanation:

Since AB = BC then the triangle is isosceles and the base angles are congruent, that is

∠ DAB = ∠ DCB = 52°

Subtract the sum of the base angle from 180° for ∠ ABC

∠ ABC = 180° - (52 + 52)° = 180° - 104° = 76°

Note that ∠ ABD = ∠ CBD, thus

x = 76 ÷ 2 = 38

BD bisects the side AC, thus DC = AD = 4

Thus y = 4

+31 +31

-31 and +31, cancel out so we're left with...

x = 143
