To find the y-intercept of the function
, we need to determine the value of
when
.Substitute
into the equation:
Since any number raised to the power of 0 is 1, we have:
Simplify the right side:
Now, solve for
by dividing both sides by 3:
Therefore, the y-intercept of the function is at the point \((0, 2)\).On the graph, plot the point at the coordinates \((0, 2)\). This is where the line crosses the y-axis.
