Use a Table of Values to Graph the Equation y=2f(x)

$y = 2 f (x)$

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = 2 f (- 2)$

Solve the equation for $y$ .

Tap for more steps…

Remove parentheses.

$y = 2 f (- 2)$

Multiply $- 2$ by $2$ .

$y = - 4 f$

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = 2 f (- 1)$

Solve the equation for $y$ .

Tap for more steps…

Remove parentheses.

$y = 2 f (- 1)$

Multiply $- 1$ by $2$ .

$y = - 2 f$

Substitute $0$ for $x$ and find the result for $y$ .

$y = 2 f (0)$

Solve the equation for $y$ .

Tap for more steps…

Remove parentheses.

$y = 2 f (0)$

Multiply $2 f (0)$ .

Tap for more steps…

Multiply $0$ by $2$ .

$y = 0 f$

Multiply $0$ by $f$ .

$y = 0$

Substitute $1$ for $x$ and find the result for $y$ .

$y = 2 f (1)$

Solve the equation for $y$ .

Tap for more steps…

Remove parentheses.

$y = 2 f (1)$

Multiply $2$ by $1$ .

$y = 2 f$

Substitute $2$ for $x$ and find the result for $y$ .

$y = 2 f (2)$

Solve the equation for $y$ .

Tap for more steps…

Remove parentheses.

$y = 2 f (2)$

Multiply $2$ by $2$ .

$y = 4 f$

This is a table of possible values to use when graphing the equation.

$\begin{array}{c} x & y \\ - 2 & - 4 f \\ - 1 & - 2 f \\ 0 & 0 \\ 1 & 2 f \\ 2 & 4 f \end{array}$
