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.
Answer:
it is an enlargement with a scale factor greater than one.
Step-by-step explanation:
you can tell this, because the pre-image is smaller than the image, and its more than double the size :)
i would help you but i cannot see the image.
Answer:
Each minute Seung fills one less bag than Razi.
Step-by-step explanation:
Find the rate of change.
<u>Razi's rate of change:</u>
<u>Seung's rate of change:</u>
This means Razi packs 4 bags per minute, Seung packs 3 bags per minute.
<u>Difference</u> = 4 - 3 = 1 bag
Each minute Seung fills one less bag than Razi.
