derivative of e^x(x-7)

Solution

\frac{d}{d x} (e^{x} (x - 7))

Solution

e^{x} x - 6 e^{x}

Solution steps

\frac{d}{d x} (e^{x} (x - 7))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = e^{x}, g = x - 7

= \frac{d}{d x} (e^{x}) (x - 7) + \frac{d}{d x} (x - 7) e^{x}

\frac{d}{d x} (e^{x}) = e^{x}

\frac{d}{d x} (x - 7) = 1

= e^{x} (x - 7) + 1 \cdot e^{x}

Simplify

e^{x} (x - 7) + 1 \cdot e^{x} : e^{x} x - 6 e^{x}

= e^{x} x - 6 e^{x}
