How many terms are in the expression 1/2 - 18y + 9z- 2

There are three terms1/2 and -18y and 9z and -2

Step-by-step explanation:

A term is separated by a - sign or a + sign. In this expression there are 2 (-) signs and 1 ( +) sign. 2+1 = 3 so there are three terms.

  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.

it is 570
