The y-intercept of the graph of the equation is -18
<h3>What is an intercept?</h3>
An intercept is a point where the tangent to a curve or a straight line touches the x-axis or the y-axis.
Analysis:
y = 6(x-1)(x + 3)
y = 6(
+ 3x -x -3)
y = 6(
+2x -3)
y = 6
+12x -18
The y-intercept of the equation occurs at x = 0
Therefore y = -18.
In conclusion, the y-intercept is -18.
