PLEASE HELP Use interval notation to determine where f(x) > 0.
Use interval notation to determine where f(x) > 4.
Use interval notation to determine where f(x) < 5.

THANK YOU

Step-by-step explanation:

a) f(x) > 0 for all x: (-∞, ∞)

__

b) f(x) > 4 for x < 3 and x > 5: (-∞, 3) ∪ (5, ∞)

__

c) f(x) < 5 for 2 < x < 6: (2, 6)

Comment on the notation

The brackets are round brackets (parentheses) because the end points are not included in the interval. The first number corresponds to the left end of the interval on the number line. The second number corresponds to the right end of the interval on the number line. When intervals are disjoint, their union is indicated with the appropriate symbol.

If the end number is included in the interval, a square bracket is used:

  1 < x ≤ 3  ⇒  (1, 3]

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

to complete this square you have to rotate about the origin 270 degrees clockwise.
