WebGraph the equation. y=-2 (x+5)^2+4 y = −2(x + 5)2 + 4 This equation is in vertex form. y=\goldD {a} (x-\blueD h)^2+\greenD k y = a(x − h)2 + k This form reveals the vertex, (\blueD h,\greenD k) (h,k), which in our case is (-5,4) (−5,4). It also reveals whether the parabola opens up or down. Since \goldD a=-2 a = −2, the parabola opens downward. WebPlot the ordered pair 6, comma negative 8 into the coordinate plane. So this is a coordinate plane right over here. The horizontal axis here, this is the x-axis. The vertical axis here is the y-axis. And the convention, when we get an ordered pair like this, is that the first coordinate is the x-coordinate, and the second coordinate is the y ...

WebUse the graph to find an approximate solution to 3/2 to the x is equal to five. So pause this video and try to do this on your own before we work on this together. All right, now let's work on this. So they already give us a hint of how to solve it. They have the graph of y is equal to 3/2 to the x. They graph it right over here. WebGraphing functions is drawing the curve that represents the function on the coordinate plane. If a curve (graph) represents a function, then every point on the curve satisfies the function equation. For example, the following graph represents the linear function f (x) = -x+ 2. Take any point on this line, say, (-1, 3). churchill veterinary san antonio
