derivative of f(x)=7x

derivative of

f (x) = 7 x

7

Solution steps

\frac{d}{d x} (7 x)

Take the constant out:

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

= 7 \frac{d x}{d x}

Apply the common derivative:

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

= 7 \cdot 1

Simplify

= 7

y^{^{''}} + 80 y^{^{'}} + 20 y = 0

\int \frac{( - 2 u ^{4} + 3 u )}{u ^{2}} d u

x \to \frac{1}{4} lim (x^{2} + 3 x)

\frac{d}{d x} (- \frac{3 e ^{\frac{3}{x}}}{x ^{2}})
