2 to the 2nd power is also a way of saying 2 times 2. So, 2 to the 2nd power is 4.

I guess, though product is also involved lim(2x) = 2 * lim(x) But I guess C is closest.
*Thursday, March 20, 2014 at 1:25pm*

yes, that would be correct.

*Thursday, March 20, 2014 at 12:58pm*

**Math - PreCalc (12th Grade)**

So it is D?
*Thursday, March 20, 2014 at 12:51pm*

**Math - PreCalc (12th Grade)**

You are correct; you cannot divide by zero. So, f(x) is not defined for x=4. However, for any other value of x, f(x) = (x-4)(x+4)/(x-4) = (x+4) So, if you define f(4) = 8, then f(x) = x+4 for all values of x, and is now continuous.
*Thursday, March 20, 2014 at 12:43pm*

**Math - PreCalc (12th Grade)**

I chose C. Is that correct?
*Thursday, March 20, 2014 at 12:39pm*

**Math - PreCalc (12th Grade)**

What value must be defined for f(4) to remove the discontinuity of this function at x=4? f(x)=(x^2−16)/(x−4) A) 0 B) 4 C) -4 D) 8 E) -8 f(4)=(4^2−16)/(4−4) f(4)=0/0 you can't divide by zero. I don't understand the question.

*Thursday, March 20, 2014 at 12:29pm*

**A Peculiar Question**

Is either a B+ or an A- considered a terrible grade? If I received a B+ for two essays that I was assigned and then an A- for another, will these grades ultimately cause a decrease in my GPA? I want to enter into either a film or art college, and I want to retain my 4.0 GPA ...

**A Peculiar Question**

A B+ is well above average, so it's a good grade. We can't know whether it will affect your report card because we don't know your other grades -- both in this class and in others.

**A Peculiar Question**

Thank you!! you really are helping me alot.
*Wednesday, March 19, 2014 at 12:21pm*

**Math - PreCalc (12th Grade)**

Ummm. Do you not think it would be A? I explained how the discontinuity could be removed. Hence, it is removable.

*Wednesday, March 19, 2014 at 12:05pm*

**Math - PreCalc (12th Grade)**

at x=5, f(x) = 0/0, or undefined. At any other value, though, f(x) = (x-5)(x+5)/(x-5) = x+5 So, f(x) is undefined only at x=5. By defining f(5) = 10, the discontinuity is removed. f(x) = x+5 for all x.
