What are the x- intercepts?
The point(s) where the parabola crosses the X-axis (at this point the "y" will be 0.)
Also known as zeroes, solutions, or roots.
Parabolas can have two x-intercepts, one x-intercept or no real solutions(o x-intercepts).
Also known as zeroes, solutions, or roots.
Parabolas can have two x-intercepts, one x-intercept or no real solutions(o x-intercepts).
To find x-intercepts there are multiple methods you can use. Such as factoring, grouping,the quadratic formula,completing the square or looking at a graph.
What is the y-intercept?
The point where the graph crosses the Y-axis (at this point "x" will be 0.")
Parabolas have a y-intercept.
The equation must be in expanded form in order to find the y-intercept from the c-value.
The y-intercept is the "c" value of the quadratic equation. When a "c" value is not present the y-intercept is (0,0).
y= ax² + bx + c
EXAMPLE:
y=24x²-7x+13 <---------- the y-intercept is (0,13)
