Question

Brianna is graphing the function f(x) = x2 + 6x + 5. What x-intercepts should Brianna use to graph f(x)?

Answer 1

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

Answer:

-5 -1
