The twicedifferentiable function f is defined for all real numbers and satisfies the
following conditions: f(0) = −2 ,
f′(0) = 3, f"(0) = −1 .
A. The function g is given by g(x) = tan(ax) + f(x) for all real numbers, where a is a
constant. Find g′(0) and g"(0) in terms of a.

just differentiate and let x=0. \(g'(0) = a sec^2 (0) +f'(0)\) where \(sec^2(0)=1\), so, \(g'(0) = a +3\)

Can you help me with the second part too? The function h is given by ℎ(x) = sin(kx) ∙ f(x) for all real numbers, where k is a constant. Find ℎ′(x) and write an equation for the line tangent to the graph of h at x=0. please?

sure...for this question, you too find the h'(0) to get the gradient at that pt, but this time you also have to evaluate h(0) to get the point(0,h(0)) \(h'(0)=k \cos (0) f(0) + f'(0) sin(0)\) \(h'(0)=2k\)
