Find the slope of the tangent line to the graph of

$f(x)=-x^2+4\sqrt{x}$ at $x=4$

$a.\ 8\quad b.\ -10\quad c.\ -9\quad d.\ -5\quad e.\ -7$

however not asked for here but I forgot how to find $b$ of $y=-7x+b$

$f'(x)=-2x+\frac{2}{\sqrt{x}}$

$m=f'(4)=-2(4)+\frac{2}{\sqrt{4}}=-7$ which is (e)

$m=f'(4)=-2(4)+\frac{2}{\sqrt{4}}=-7$ which is (e)
