Number Line:
Closed Circles are used when signs are "≤" or "≥"
Open Circles are used when signs are "<" or ">"
The graph of x > -1 on a number line would be towards the right from -1 with open circle as the sign is ">"
Graph should look like this:
In the xy-plane, what is the y-intercept of the graph of the equation y = 6 (x - 1) (x + 3)?
1 answer:
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.
