Which of the following is an x-intercept of the graph of the function shown below?
DaniilM [7]

Answer: Second option.

Step-by-step explanation:

By defintion, a Quadratic function is a polynomial of degree 2 and it has the following form:

f(x)=ax^2+bx+c

Therefore, the function given is Quadratic. This is:

f(x)=x^2 + 6x +9

The steps to find the roots (or the x-intercepts) of the function, are:

1. You must substitute f(x)=0:

0=x^2 + 6x +9

2. Now, you can factor the Quadratic equation. Choose two numbers whose sum is 6 and whose product is 9. Notice that:

3+3=6\\3*3=9

Therefore,  you will get a "Double root".

4. So the solution is:

(x+3)^2=0\\\\x=-3
