Question

Brianna is graphing the function f(x)=x^2+6x+5 what is the x intercepts should Brianna use to graph f(x)

Answer 1

-5, x=-1

Explanation:

to find t he x intercepts factor the quadratic and set them = to 0

x^2 +6x+5 = 0

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

x+5 = 0 x+1=0

x=-5 x=-1

the x intercepts are -5, x=-1

Answer 2

(x+5)(x+1). so use -5 and -1
