Pls help NOTE: When using interval notation in WeBWork, remember that:You use 'INF' for o and '-INF' for -oo.And use 'U' for the union symbol.Enter DNE if an answer does not exist.f(x) = 2 sin x + 3 cos x,on (-x, x)a) Determine the intervals on which f is concave up and concave down.f is concave up on:f is concave down on:b) Based on your answer to part (a), determine the inflection points of f. Each pointshould be entered as an ordered pair (that is, in the form (x, y)).(Separate multiple answers by commas.)c) Find the critical numbers of f and use the Second Derivative Test, when possible,to determine the relative extrema. List only the x-coordinates.Relative maxima at:(Separate multiple answers bycommas.)Relative minima at:(Separate multiple answers bycommas.)d) Find the x-value(s) where f'(x) has a relative maximum or minimum.f' has relative maxima at:(Separate multipleanswers by commas.)f' has relative minima at:(Separate multipleanswers by commas.)
