Find an equation of the tangent line to the graph of y = e^(−x^2) at the point (5, 1/(e^25)). My work: y' = -2xe^(-x^2) y' when x = 5 = -10e^25 y - (1/e^25) = -10e^25 * (x - 5) y = (-10e^25) (x - 5) + (1/e^25) This is incorrect. How?

Use the four-step process to find the slope of the tangent line to the graph of the given function at any point. f(x) = 16 - 10 x Step 2: f(x + h) - f(x) = Step 4: f'(x) = lim(h->0)(f(x + h)- f(x))/h =
