y = ax2 + bx = c In this example, you’ll need to use the quadratic formula to find the x-intercept. Next: Quadratic Formula Y-Intercept (Definition) The y-intercept is the point where a graph crosses the y-axis. On the graph below, the plotted line crosses the y-axis at y =...
Apply the quadratic formula, which gives the roots p and q. Then, the intercept form of the parabola is y = a(x - p)(x - q) What is intercept form? A quadratic function has general form y = ax^2 + bx + c. The intercept form is y = a(x - p)(x - q), where p and ...

I'm assuming y=-(x+8)2+7 is the equation since the above equation is confusing. The problem is wanting the form, y = ax2+bx+c -(x2+16x+64)+7 = -x2-16x-64+7 = -x2-16x-57 y = -x2-16x-57 Upvote • 0 Downvote Add comment Still...
分析设抛物线的解析式为y=ax2+bx+c。若按常规解法,则需要解关于a、b、c的三元一次方程组,变形过程比较繁杂;若巧用抛物线的对称性,解法就简捷了。因为抛物线的对称轴为x=1,与x轴两交点间的距离为4,由抛物线的对称性可知,它与x轴交于A(-1,0)、B(3,0)两点。于是可设抛物线的解析式为y=a(x+1)(x-...

The graph of a quadratic function is a parabola. If the parabola opens upwards, that is, if the leading coefficient is positive, then the minimum value of the function will be at the vertex, which may be found from the general form {eq}y=ax^2+bx+c {/eq} using {eq}x...

Use the quadratic formula to find the value of the variable. Factor the equation and find the values of the variable. If you factor the quadratic equation, it is done through a remarkable product or a common term. It must be in the general form {eq}ax^{2}+bx+c=0. {/eq} ...
