Graph each equation steps
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. WebIn an equation of the form y = mx, m is the slope of the graph of the equation. Example 1 Sketch the graph of y = 6x and give the slope of the line. Solution We first make a table showing three sets of ordered pairs …
