My English lesson EXERCISES FILL IN THE GAPS 1. A function y = f(x), defined at least in the interval [a ; b], and a point x0 ........................., the function f is said to be derivable in .............., if there exists a ......................... limit: f (x 0 .........................) f(.........................) f (x 0) = lim __________________________ ......................... h 2. Link each function to its graph and identify features in each one about continuity and derivability at the indicated points: b. y = |x4 4 x2 1| graph a. y = | 2x + 4| graph y 1 1 O I. ............................... y 1 2 x in ...............................
