Answer:
Step-by-step explanation:
y = x^2 - x - 2 is a quadratic function. It's easily factorable: y = (x + 1)(x - 2). Setting this result equal to zero yields the x-intercepts: -1 and 2. This matches the x-intercepts shown on the graph.
The axis of symmetry, x = -b/(2a), derived from the coefficients 1, -1 and -2 of this particular function, is x = 1/2. This x = 1/2 is also the x-coordinate of the vertex. To find the y-coordinate of the vertex, we evaluate y = x^2 - x - 2 at x = 1/2, obtaining:
y = (1/2)^2 - (1/2) - 2, or y = 1/4 - 1/2 - 2, or -2 1/4. This does not quite agree with the y value (-2) shown in the diagram, but is close.

Answer:
The answer is D, 43 
Step-by-step explanation:
If the pile gets bigger by 8 
each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8 
by 3 to find out how much the pile increased by.
8 × 3 = 25 
Now, you need to add this to your initial value to get the answer.
25 + 17 = 42 
Now simplify.
43
The fraction is 23/50
Here is your decimal also 0.46
And for the percent you just have to move the decimal 2 places to the right and you will get 46%
