Use the limit definition to compute the derivative of the function
f(x)=\sqrt(x 4)
at
x=1
. (Use symbolic notation and fractions where needed.)
f^(')(1)=(1)/(2\sqrt(5))
Correct Answer Find an equation of the tangent line to the graph of
f
at
x=1
. (Use symbolic notation and fractions where needed.)
y=y=(1)/(2\sqrt(5))x (2\sqrt(5)-1)/(2\sqrt(5))
Incorrect Answer
