The vertex-form equation is
y = a(x+1)² -16
Putting in the y-intercept values, we have
-15 = a(0+1)² -16
1 = a . . . . . . . . . . . add 16
Then the x-intercepts can be found where y=0.
0 = (x+1)² -16
16 = (x+1)²
±4 = x+1
x = -1 ± 4 =
{-5, 3}
Answer:
its you again
Step-by-step explanation:
if they have the same amount of dashes on the same sided they are congruent
does that answer your question
Positive 14/472 (because of rise over run when finding slope)
Answer:It should be D E F since they all are closer to 1
