Consider the following function:
Determine the points of intersection with x.
To solve this problem, we'll need to determine where the function intersects the x-axis, which occurs where .
Let's work through the solution:
Therefore, the two points of intersection with the x-axis are and .
This matches with choice 2, thus confirming the correct option.
Thus, the points of intersection with the x-axis are and .
The following function has been graphed below:
\( f(x)=-x^2+5x+6 \)
Calculate points A and B.
X-intercepts are points where the graph crosses the x-axis. On the x-axis, the y-coordinate is always 0, so we set to find where this happens.
You'll need to factor it first or use the quadratic formula. Factored form like makes finding x-intercepts much easier using the zero-product property.
No! A quadratic function can have at most 2 x-intercepts. It might have 2 (like this problem), 1 (touching the x-axis), or 0 (never crossing the x-axis).
Remember that x-intercepts always have y = 0. Look for points in the form where the y-coordinate is zero. Points like (0,1) or (1,1) cannot be x-intercepts!
They're the same thing! Roots, zeros, and x-intercepts all refer to the x-values where . The x-intercepts are just the coordinate points: (root, 0).
