Can anyone me factor. 3n4+21n3+27n2 enter your answer in the box.

3n^4 + 21n^3 + 27n^2

3n^2(n^2 + 7n + 8)

3n^2(n+7)(n+1)

Ibelieve a is the correct answer because 3 is the y-intercept you can see it from the graph. so from here the answers could only be a and c. they are differently at the sign.substitute x with 1so the equation for a is 3*(1.4)^x3*(1.4)^1 = 4.2look back at the graph it is true that when x= 1 y= 4.2if you use equation from c. when x= 1 then y will be negative number which is falseso correct answer is a

Ais the answer for your question
