If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.
Answer:
Yes
Step-by-step explanation:
Tan = sin / cos
If sin is negative, ans cos is negative, then tangent is positive.
Tan= (-)/(-) = (+)
Standard I believe tell me if I’m wrong
Answer:
Step-by-step explanation:
(3, 0) (0, 2)
(2-0)/(0-3) = 2/-3= -2/3
y - 0 = -2/3(x - 3)
y = -2/3x + 2
