Consider the following equation: f′(a)=limh→0 (f(a+h)−f(a))/h let f(x)=3√x if a≠0, use the above formula to find f′(a)= show that f′(0) does not exist and that f has a vertical tangent line at (0,0)

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

What can each term of the equation be multiplied by to eliminate the fractions before solving? x – + 2x = + x 2 6 10 12

Ithink i know it but i want to be sure so can you me out ?
