limit as x approaches a of 2f(x)

x \to a lim (2 f (x))

2 f (a)

Solution steps

x \to a lim (2 f (x))

Plug in the value

x = a

, assuming the function is continuous at this point

= 2 f (a)

\frac{d}{d x} (cos (x + 1))

t^{2} \frac{d y}{d t} = - y

\frac{d}{d x} (6 x y + 5 x^{2})

roo t s co tan (x)

f (x) = e^{2 x} + 2 e^{2 x} x

What is the limit as x approaches a of 2f(x) ?
The limit as x approaches a of 2f(x) is 2f(a)
