WebThe answers that you found (for k) are when the discriminant equal 0 (b^2-4ac=0) -- which means that the function has only one solution. When you graph (k+4)^2-4(k+7), you get a convex parabola with vertex (-2,-16) and x-intercepts at (-6,0) and (2,0). That implies … Web使用包含逐步求解过程的免费数学求解器解算你的数学题。我们的数学求解器支持基础数学、算术、几何、三角函数和微积分 ...
