Question

determine the points of discountinuty of the function f and naturvof discountunuity at each of those points f(x) = -x square when x less then equal to 0 , 4-5x , 3x-4x square -12x+2x

Answer 1

f(x) = -x² 

We can plot this curve as

Hence, the curve is continuous entirely on all real plane. 

Hence, No point of discontinuity exists for this curve.
