EXAMPLE 10 If f(1 + x) = x + 1, then f(2-h). Substitute x =1-h in given and get the value of f (2-h). Sol. We have, f(1 + x) = x2 +
SOLUTION: graph f(x)=1/x-4
SOLUTION: Hello! How do I graph f(x)=(x^2-1)/(x+1)? What does lim(x->1) ( x^2-1)/(x+1) equal? I graphed the function with a discontinuity at x=-1, but I'm not sure how my second questio
