Question 3: For a linear equation y = 2x + 6, find the point where the straight line meets y-axis on the graph.Answer: On y-axis, the x-coordinate of the point is 0. Therefore, we can find the intersection point of y-axis and y = 2x + 6 by simply putting the value of x ...
Find the total area of the region between the x-axis and the graph of y=x2−3x,−4≤x<1. Integrals: As per fundamental theorem of calculus,for a given continuous function in an given interval let f(x);a≤x≤b the area bounded is denoted by: ...
A(1, 0), B( -3, 0) C. A( -3, 0), B(1, 0) D. A(3, 0), B( -1, 0) 相关知识点: 试题来源: 解析 A。先令 y = 0,即 x^2 - 2x - 3 = 0,因式分解得 (x + 1)(x - 3) = 0,解得 x = -1 或 x = 3,所以交点坐标为 A( -1, 0), B(3, 0)。反馈 收藏 ...
相关知识点: 试题来源: 解析 A。本题考查二次函数图像的开口方向。对于二次函数 y = ax^2 + bx + c,当 a > 0 时,图像开口向上;当 a < 0 时,图像开口向下。在函数 y = x^2 + 2x - 3 中,a = 1 > 0,所以图像开口向上。反馈 收藏 ...
