To find the x-intercept of a function, set y to 0 and solve for x. To find the y-intercept of a function, set x to 0 and solve for y. How do you find the intercepts of a function? The intercepts of a function may be found graphically by examining where the line crosses the x...
If we first checked x=0 (the y-axis intercept) and found y=0 satisfied this, we would still need to solve for y=0 because we could possibly have more solutions for x such as in the case of quadratics. Now, the reason why we wouldn't need to check x=0 (as opposed needing to ...
Explore – Axis of Symmetry x=-b/2a The ‘b’ moves the AOS left/right Solving Quadratic Functions (ax 2 + bx + c = 0) Since y = ax 2 + bx +c, by setting y=0 we set up a quadratic equation. To find the solutions means we need to find the x-intercept. Since the graph i...
My problem is that whenever I have to use cubic functions - whether it's finding the roots (when dy/dx kis a cubic function) or finding the x-intercepts... With quadratic functions I usually use the quadratic formula. I try to figure out how to factor these equations in my head...
Since 5 is a real number, it is also an xintercept of the graph of the function . Let's look at the graph of Notice that the x- intercept is also the vertex point as well as the Zero of the quadratic function. Example 4: Find the Zeros of the polynomial function Since the ...

I'll start by using the Rational Roots Test (and maybe a quick graph on my calculator) to find a good value to test as possibly being a zero (that is, possibly an x-intercept on the graph). I'll try x = 1: This division gives a zero remainder, so x = 1 must be a zero, ...
Example 2: Finding the Roots of a Polynomial Find the roots of x 2 – 2x – 4 with the quadratic formula: 2 2 2 4 1 4 2 1 x 2 20 2 2 2 5 2 1 5 x 0, 1, 1 5, &1 5 x Therefore, the four roots are: Find the roots of y=x 4 – 3x 3 – 2x 2 + 4x. Current ...
