Question 16 • Algebra I

Brianna is graphing the function f of x is equal to x squared plus 6 x plus 5 What x -intercepts should Brianna use to graph f of x ?

Answer
A
negative 5 and 1
B
negative 1 and 5
C
negative 5 and negative 1
D
1 and 5

Explanation

To find the x-intercepts, set f(x) equal to 0: x² + 6x + 5 = 0. Factoring gives (x + 1)(x + 5) = 0, so x = −1 or x = −5. Brianna should use negative 5 and negative 1, choice A.
