A parabola is the graph of a quadratic function, which is a type of function where the highest power of the variable (usually represented by
�
x) is squared. Here are the main points about the parabola of a quadratic function:
Shape: A parabola is a symmetrical curve that looks like a U or an upside-down U. It can open upwards or downwards.
Vertex: The highest or lowest point on the parabola is called the vertex. If the parabola opens upwards, the vertex is the lowest point, and if it opens downwards, the vertex is the highest point.
Axis of Symmetry: A parabola has a line of symmetry called the axis of symmetry. It passes through the vertex and divides the parabola into two equal halves.
Intercepts: A parabola can intersect the x-axis, the y-axis, or both. The points where it intersects the x-axis are called x-intercepts or roots. The point where it intersects the y-axis is called the y-intercept.
Direction: The direction in which the parabola opens depends on the sign of the coefficient of the squared term in the quadratic function. If it's positive, the parabola opens upwards; if it's negative, the parabola opens downwards.
Understanding these basic concepts can help you analyze and graph quadratic functions, which are widely used in mathematics and real-life applications.

舒适热玛吉 体验过就爱上！！
近hen火的Thermage FLX-UP舒适热玛吉我来do了
这个应该是新升级的了
升级以后的操作方案可以根据每个人的实际情况来定制
临️的操作方案也有升级
让体验感变好，效果也会更好
我做的是Thermage FLX-UP舒适热玛吉900发的
做的面部+颈部
整个过程都是不需要fu麻的
仪器上脸大部分区域就是温温热热的感觉
敏.感区域y生还加入了提捏的手法也不怎么疼哦
全程我都是躺着享受
刚做完半边脸看效果就有对比
���我是属于法令wen、颈wen比较y重的
do完以后能看见脸上皮肤提拉 法令w也淡了不少
y生说还仅仅只有20%的效果
等到三个月以后效果才是巅️峰
浅浅期待一下8

固定脚VS滑轮脚 | 椅子应该选哪种❓
滑轮脚：360°转动，更加方便灵活。
固定脚：不晃动，更加稳固安全。
选办公椅的时候总在固定脚和滑轮脚之间犹豫不决❓
其实两者各有千秋，合适才是最优解。
