Single Variable Calculus, Chapter 2, 2.5, Section 2.5, Problem 41

Determine the value of the constant c that makes the function f(x)={cx2+2x if x<2x3cx if x2 continuous on (,)

Based from the definition of continuity,
The function is continuous of at a number if and only if the left and right hand limits of the function at the same number is equal. So,


lim


Therefore,
The value of c that would make the function continuous on (-\infty, \infty) is \displaystyle \frac{2}{3}
