(1 point) Find a value of the constant k, if possible, at which kx2 x56 f(x):{9x+k x>6 is continuous everywhere. k = none (enter "none" if no value). (1 point) For what value of the constant c is the function f continuous on the interval (-co, co). f(x) = x2 - 2, x C C=(1 point) Given the interval(s) on which the function is continuous. f(x) = ex - In(x - 5) NOTE: When using interval notation in WeBWork, remember that: You use 'INF' for co and '-INF' for -co. And use 'U' for the union symbol.(1 point) Given the interval(s) on which the function is continuous. f(x) = V7 -ex NOTE: When using interval notation in WeBWork, remember that: You use 'INF' for co and '-INF' for -co.
