2. The axis of symmetry of the parabola y = -1/2x2 + 9 is: a) x= 9
b) x = -9
c) x=0
d) x = -1/2

Please type the answer

y=mx+

  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.
