The function h : R - R defined by 2 2 - x - 20 h(ac) = x +4 c = -4 has a discontinuity at -4. At this discontinuity the left and right hand limits of h exist but are not ... If the function / can be turned into a continuous function by redfining the value of h(-4) only, enter that value below. If it can't be turned into a continuous function by redefining only h(-4), enter "none" below. Enter your answer as an exact fraction, not as a decimal approximation. h (-4)
