If its equation is y=ax^2+bx, what are possible values of a and b? () A. a=4;b=-8 B. a=4;b=0 C. a=-4;b=-8 D. a=-4;b=0 相关知识点: 试题来源: 解析 A 结果一 题目 Consider the following graph.If its equation is , what are possible values of and ? ( )A. ;B...
A function such as y = ax2 + bx + c is continuous. This is useful in nature, since an extended object such as a log is often partly hidden by branches, and the curve fitting to samples of the log allows occluded parts to be implied. An equation for a curve is ...
What is the quadratic equation whose roots are -3, -1 and has a leading coefficient of 2 with x to represent the variable? What is the quadratic equation written in standard form whose roots are -2 and 3? What is the linear term in a quadratic equation? What is the quadratic formula?
To find the differential equation of the curve given by y=ax2+bx, we will follow these steps: Step 1: Differentiate the equation with respect to xWe start with the equation:y=ax2+bxDifferentiating both sides with respect to x:dydx=2ax+bThis is our first equation. Step 2: Differentiate...
