How can we write 128 in exponent form?

2⁷

Step-by-step explanation:

                    128

128 = 2 * 2 * 2 * 2 * 2 * 2 * 2

     = 2⁷

  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.

answer:

a=9
