If we set the equation equal to 0, we can factor it to find its roots:
x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2
This graph has one root, a double root, at -2. This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)
Answer:
45
Step-by-step explanation:
Answer:
y=3/2
Step-by-step explanation:
This line's slope is perpendicular to -2/3 and its y intercept is 0.
Step-by-step explanation:
y-y₁=m(x-x₁)
1-(-4)=m(4-3)
5=m
