Question

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

Answer 1

The answer is
–5 and –1
proof
for  f(x) = x2 + 6x + 5, f(-5)=25-30+5 = 0, x=-5, y=0
     f(-1)= 1-6+5=6-6=0, x=-1, and y=0
the x-intercepts are –5 and –1

Answer 2

Answer:

The answer is A
