a differentiable function f is defined on -7 < x <7 has f(0) = 0 and f'(x)=2x sinx-e^-x^2 + 1 (Note: the following questions refer to f, not to f') a) Describe the symmetry of f b)on what intervals is f decreasing? c)for what values of x does f have a relative maximum? Justify your answer. d)How many points of inflection does f have? Justify your answer.
\[f'(x)=2x sinx-e ^{-x ^{2}}+ 1\]
