To find the value of y at x=2 from the equation y=2x, follow these steps: 1. Identify the equation: The given equation is y=2x. 2. Substitute the value of x: We need to find y when x=2. Substitute x=2 into the equation: y=2(2) 3. Perform the multiplication: Calculate 2×...
Graph the equation x= y^2. Find any intercepts and check for symmetry first. 相关知识点: 试题来源: 解析 The lone intercept is (0, 0). The graph is symmetric with respect to the x-axis since x=(-y)^2 is equivalent to x= y^2. The graph is not symmetric with respect to the y...
