The equation y equals 3 times (x plus 2) squared minus 7 sits over the forms grouped by family, linear, quadratic, exponential, and circle, and the vertex form lights up. Then, for y equals 5 times 0.8 to the x, the exponential decay form is picked. Finally, for the parabola y equals x squared plus 6x plus 5, answer which equivalent equation shows its vertex as constants, using the buttons after the picture.
