For the following quadratic function, find the axis of symmetry, the vertex and the y-intercept. y = x^2 + 8x + 12 A) axis of symmetry: x = 4; vertex: (4,60); y-intercept: 12
B) axis of symmetry: x = -8; vertex (-8,12); y-intercept: -8
C) axis of symmetry: x = -4; vertex: (-4,-4); y-intercept: 12
D) axis of symmetry: x = 8; vertex: (8,140); y-intercept: 8

C

Step-by-step explanation:

-4 is the x-axis on the vertex and 12 is the number where the graph crosses the y-axis

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
