Evaluate the Function y=3^x for x=2

$y = 3^{x}$ for $x = 2$

Step 1

Replace all occurrences of $x$ with $2$ in each equation.

Replace all occurrences of $x$ in $y = 3^{x}$ with $2$ .

$y = 3^{2}$

$x = 2$

Simplify the right side.

Raise $3$ to the power of $2$ .

$y = 9$

$x = 2$

$y = 9$

$x = 2$

$y = 9$

$x = 2$

Step 2

The solution to the system is the complete set of ordered pairs that are valid solutions.

$(2, 9)$
