The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
Answer:
Graph 4
Step-by-step explanation:
It crosses at 1 (y-intercept) and has a slope of 1/2
Answer:
x = -1 or x = -7
Step-by-step explanation:
y = (x + 4)^2 - 9
To find x-intercept, set y = 0
=> (x + 4)^2 - 9 = 0
=> ( x + 1)( x + 7) = 0
=> x = -1 or x = -7
