ok. Like here in this example... 1.548937075 x 10 to the 12th. Would you do the problem 1.548937075 x 10 to the 12th which would be 1,548,937,075,000 first before you rounded. I think in the number that I got (1,548,937,075,000) there are 10 significant numbers??

Thursday, March 20, 2014 at 1:25pm

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.

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.
