x2−y=9 Change the given equation into y=f(x) form. y=x2−9 Finding X-intercept(s): Step 2:To solve for the x-intercept(s), equate y=0 and solve for x. (x1,0),(x2,0) x2−9=0 x2=9 x=+3,−3 X-intercepts=(+3,0)(−3,0) ...
Find the vertex and (align*)x(align*) -intercepts of the function (align*)y=(x-4)^2-9(align*) .相关知识点: 试题来源: 解析 Vertex: (align*)(4,-9)(align*) ; x-intercepts: (align*)(1,0)(align*) and (align*)(7,0)(align*) ...
thereis no way for there to be x-intercepts for this problem.Step 4In this case we didn't have x-intercepts and the y-intercept also happens to be the vertex.So,at thispoint we have only have one point on the graph.To get points on either side of the vertex all we needto do ...
