    Courtesy of Texas Instruments y = (x − 3)2 − 1 y = (x + 3)2 − 1 y = (x − 4)2 − 2-my answer y = (x − 4)2 + 8

    next time just type the numbers please. it's a lot easier to decipher. If it turns at (-3, -1) that's the vertex, so it should be the 2nd choice

    f(x)+k moves the function down k units. You want the one that makes -1*f(x)

    rate of change just means slope. \[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]
