Which of the following is a key property of the quadratic parent function? A. It is NOT a parabola

B. Its vertex is in quadrant III.

c. It is in quadrants I and II.

D. It is NOT a function

C

Step-by-step explanation:

First, note that the parent quadratic function has the equation .

All quadratic functions are parabolas. Eliminate A.

The vertex of is on the origin point (0,0), not in Quadrant III. Eliminate B.

is definitely a function. Eliminate D.

The correct answer is C. The function covers Quadrant I and II.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
