derivative of f(x)=3x

derivative of

f (x) = 3 x

3

Solution steps

\frac{d}{d x} (3 x)

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 3 \frac{d x}{d x}

Apply the common derivative:

\frac{d x}{d x} = 1

= 3 \cdot 1

Simplify

= 3

(- 1, 1), (4, 5)

(5, 0)

y = 2 (5 x + 1) + 3 (5 x + 3)

x = 10

(- 2.3) (10.3)
