Question

For each problem, find the: x and y intercepts,asymptotes, x-coordinates of the critical points, open intervalswhere the function is increasing and decreasing, x-coordinates ofthe inflection points, open intervals where the function is concaveup and concave down, and relative minima and maxima. Using thisinformation, sketch the graph of the function.

1.) y = - (x^4/4) + x^2 -1

2.) y = - (1/4)x^(8/3) +4x^(2/3)

***Please show full work! Thanks!!!

I need this now!!!
