In calculus, the slope of a line, also known as the gradient is important to calculate because it explains how steep the line is. If we have an equation of a line in the form {eq}y=mx+c {/eq}, the slope of this line is calculated as {eq}\dfrac{\Delta y}{\Delta x}=m {/...
Consider the function f(x) = |x - 2|. What is the slope of the function at x = 2? A. 1 B. -1 C. D. Does not E. xist 相关知识点: 试题来源: 解析 D。解析:函数在 x = 2 处不可导,因为左导数和右导数不相等,所以斜率不存在。
