Step-by-step explanation:
use a calculator
The answer is 3x^2 + 6x + 4 (the second one)
Let's start by removing the parenthesis to get 6x + 7 + x^2 + 2x^2 - 3
Then, let's combine like terms (terms with the same variable and exponent) to get 3x^2 + 6x + 4
This is an answer in the multiple choice, so the answer is 3x^2 + 6x + 4 (the second one)
The line perpendicular to the y-axis is the x-axis.
Required equation is y = 0
