Create the equation of a quadratic function, in factored form, that has on zero of -3 and a turning point at (-1,-16). Try to determine the second zero of the parabola by think about the relationship between the first zero and the turning point.

161 to the nearest 10 = 160

161 to the nearest 100 = 200

Step-by-step explanation:

161 to the nearest 10:

Since you know that 60 is the tenth unit in this number, and 1 is the one unit, the one unit will indicate if it should be rounded up or down. If the one unit it 4 and below, the number will be rounded down. If the one unit is 5 and above, the number will be rounded up.

With this information, we know that he one unit in this number is "1", which will make the 61, be rounded down to 60, resulting in 160.

Using the same information with rounding to the nearest 100, since the tenth unit is above 5, the number will be rounded to the nearest 100, which is 200.

You use the number before the number you are trying to round, to find the nearest "_th".
