1. There is no "h" in f(x) = log(x). The question is nonsense.

2. The log function is defined for arguments greater than zero. You're probably expected to select D, though A and B could also be correct.

3. Same deal. The log function is defined for x > -2, but the domain could be restricted to x > 2. You're expected to select FALSE.

4. Same deal. Choose B, though D is also correct.

5. C is the proper choice. (See discussion of the log function, above.)

Using the equation x squared minus c equals 0 , what value of c has 9 and -9 as solutions.
Svetach [21]

9514 1404 393

Answer:

  c = 81

Step-by-step explanation:

The equation x² -c = 0 can be factored as ...

  (x -√c)(x +√c) = 0

which has roots ±√c.

The roots are given as ±9, so we have ...

  ±9 = ±√c

  c = (±9)² = 81

The value c = 81 makes the equation have ±9 as solutions.
