Step-by-step explanation:
Vertex : (2,0)
root : is at 2 on the x axis
maximum is infinity
minimum is at the x axis
like so in the picture
Looks about either 38 or 52
Answer:
The rate is usually given as a percent.
To find the discount, multiply the rate by the original price.

Answer:
-x^2 + 8x - 16.
Step-by-step explanation:
That would be -1(x - 4)^2.
= -(x^2 - 8x + 16)
= -x^2 + 8x - 16.
Answer:
C. A reflection over the line y = -x
Step-by-step explanation:
You need to reflect that over a line that goes between the two of them. That imaginary line has a rise of -1 (it goes down 1 unit) and a run of 1 (it goes one unit to the right). In other words, the slope is -1. The line should also have a y-intercept of 0 it starts at (0,0).
Put that information in slope-intercept form
y = -1x + 0
You can take out the 0 because it adds nothing to the equation, and you can remove the one because of the same reason, but leave the negative sign.
y = -x
