Evaluate the Function f(4)=(x+12)/(2x-1)

$f (4) = \frac{x + 12}{2 x - 1}$

Step 1

Replace the variable $x$ with $4$ in the expression.

$f (4) = \frac{(4) + 12}{2 (4) - 1}$

Step 2

Simplify the result.

Add $4$ and $12$ .

$f (4) = \frac{16}{2 (4) - 1}$

Simplify the denominator.

Multiply $2$ by $4$ .

$f (4) = \frac{16}{8 - 1}$

Subtract $1$ from $8$ .

$f (4) = \frac{16}{7}$

The final answer is $\frac{16}{7}$ .

$\frac{16}{7}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$\frac{16}{7}$

Decimal Form:

$2.\overline{285714}$

Mixed Number Form:

$2 \frac{2}{7}$
