brianna is graphing the function $f(x)=x^{2}+6x + 5$. what $x$-intercepts should brianna use to graph $f(x)$?\n-5 and -1\n-5 and 1\n-1 and 5\n1 and 5

Answer

Explanation:

Step1: Set the function to 0

$x^{2}+6x + 5=0$

Step2: Factor the quadratic equation

$(x + 1)(x + 5)=0$

Step3: Solve for x

$x+1 = 0$ gives $x=-1$; $x + 5=0$ gives $x=-5$

Answer:

A. -5 and -1
