f(x) is continuous when k = 1/5
suppose f(x)= sqrt of 1+3x, x>or equal to 5
k(x^2-5), x<5
for what value of k is continuous? For what value of k is f differentiable?
not even sure where to start i think i am on dealing with the second equation in this piecewise function
i know the answers are f is continuous if k=1/5 and f is differentiable if k=3/80
