Solve f_{2}|9

$$f _ { 2 } | 9$$

Differentiate w.r.t. f_2

$$9$$

Steps Using Definition of a Derivative

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 9 is 9.

$$\frac{\mathrm{d}}{\mathrm{d}f_{2}}(f_{2}\times 9)$$

The derivative of ax^{n} is nax^{n-1}.

$$9f_{2}^{1-1}$$

Subtract 1 from 1.

$$9f_{2}^{0}$$

For any term t except 0, t^{0}=1.

$$9\times 1$$

For any term t, t\times 1=t and 1t=t.

$$9$$

Evaluate

$$9f_{2}$$

Solution Steps

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 9 is 9.

$$f_{2}\times 9$$
