Answer:
Choice G
Step-by-step explanation:
Choice F would imply Circle II to I (But we are looking for I to II). Choices H and J implies translation not dilation.
Answer:
Step-by-step explanation:
slope is -3/2
y intercept is 4. y intercept is where the line crosses the y axis.
Step-by-step explanation:
that probably should be your answer
The answer is B.
If you find a common denominator, the process becomes much easier. I hope this was helpful.
Answer:
Step-by-step explanation:
Roots: set y = x^2 + 8x + 12 = 0 and solve for x: x + 6 = 0, so x = -6 is one root. The other is x = -2. The corresponding points are (-6, 0) and (-2, 0).
y-intercept: Let x = 0. Then y = 12. The y-intercept is (0, 12).
Axis of symmetry: x = -b / (2a) => x = -8/(2*1) = -4: x = -4
Vertex y-value: evaluate y at x = - 4: (-4)^2 + 8(-4) + 12 = -4: (-4, -4)
Arbitrarily chosen x value: x = 1 => 1^2 + 8(1) + 12 = 21: (1, 21)
The five points are: (-6, 0) and (-2, 0), (0, 12), (-4, -4), (1, 21). The vertex is (-4, -4). The parabolic graph opens UP.
