If a polynomial function f(x) has roots –9 and 7 – i, what must be a factor of f(x)?

i)(x-9),

ii)(x-i),

iii)(x-7+i)(x-7-i),

iv)(x-7).

A differentiable function f has the properties(i) f(x) 0 for x > x0,(iii) f(7) = 7, f'(7) = 5.Use the tangent line at (7, 7) to the graph of f to compute an approximate value for the value of x0.
