Find the sum(x2 + 2x + 3) + (3x2 + x + 1)

Sum of (x²+ 2x + 3)  and (3x² + x + 1) is:

4x²+3x+4

Step-by-step explanation:

Find the sum of:

(x²+ 2x + 3)  and (3x² + x + 1)

(x²+ 2x + 3) + (3x² + x + 1)

Combining the like terms, we get

= x²(1+3)+x(2+1)+(3+1)

=4x²+3x+4

Hence, sum of (x²+ 2x + 3)  and (3x² + x + 1) is:

4x²+3x+4

  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.
