Apr 2, 2017 · See the entire solution process below: The absolute value function takes any negative or positive term and transforms it to its positive form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent. -9 < x - 3 < 9 Add color(red)(3) to each segment of the system of inequalities to solve for x while keeping the …

Sep 25, 2015 · =color(blue)(3xsqrtx sqrt(9x^3) can be written as: sqrt(3^2 *color(blue)(x^2*x) =color(blue)(3 *x) sqrt x =color(blue)(3xsqrtx

Aug 4, 2016 · 8sin^(-1)((x-3)/3) - sqrt(9-(x-3)^2) + C I hope you like substitutions, because we're about to do a lot of them. To start, let u = x-3 implies du = dx Integral becomes: int (u+8)/(sqrt(9-u^2)) du Now we want to deal with the denominator. This type of function will often involve a trig substitution - if you learn/can derive the pythagorean identities they are very helpful in figuring …

Dec 7, 2016 · Thus, f(x) is not continuous at x=3. Bonus: Here's a tip to determine where some functions will be discontinuous. Any x-value that makes any denominator in the function equal to 0 is a point of discontinuity. So for the function above, x-3=0 when x=3, and so the function will be discontinuous at x=3.

Sep 25, 2016 · (I am assuming that we want to stay in the real numbers.) As xrarr3^-, the numerator is approaching 6 and the denominator is a positive number approaching 0. As xrarr3^-, the ratio is increasing without bound. lim_(xrarr3^-) sqrt(x^2-9)/(x-3) = lim_(xrarr3^-) (x+3)/sqrt(x^2-9) =oo

Oct 27, 2016 · x=27 Remember that in general log_b a = c means b^c=a (You really need to memorize this; it's a basic definition.)
