Step-by-step explanation:
a goes up 9 and b up 5 and c up 12 good luck
Answer:
the answer is d
because Let's see if you understood the definition of an arithmetic sequence. Which of the following is *not* an arithmetic sequence?
5, 2, -1, -4, -7, -10, -13, -16, -19...
4, 4, 4, 4, 4, 4, 4, 4, 4...
2.13, 3.34, 4.55, 5.76, 6.97, 8.18, 9.39, 10.6, 11.81...
1, 1, 2, 3, 5, 8, 13, 21, 34...
My example:
1. Get the equation in the form y = ax4 + bx + c
2. Calculate -b / 4a. This is the x coordinate of the vertex
3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.
y=2x^2 -16x +30
vertex: ( 4, -2)
Focus: (4, -15/8)
Axis of symmetry: x = 4
Directrix: y = -17/8
