Examine the piecewise graph below and evaluate f(3). Verify the identity algebraically. Use the table feature of a graphing utility to check your result numerically. Evaluate the indicated function for f(x)=x^2-1 and g(x) = x - 2 algebraically. If possible, use a graphing utili...
Use the graph of f(x), shown below, to evaluate the limit of f(x) as x approaches 0. Graph the piecewise-function and find the following limits. f(x) = -2 - x, x < -3; 4 - x^2, -3\leq x \leq 1; 2x + 1, x > 1 . a. \...
