Answer:
the answer is 4/5 because 4 divided by 5 is .80. multiply the .80 by 100 to get 80%
B. Y = <span>|x| - 2
when moving left or right...meaning moving horizontally.......the number is added inside the parenthesis.
This one is moving up or down ....meaning moving horizontally........so the number is added outside the parenthesis. If it moves up then add(+)..........if it moves down then subtract(-). The formula used for horizontal shifts is, y=lXl + k
.Here k will become negative or remain positive based on the given data.
Now,
It's a horizontal shift, so we can eliminate C and D.
It moves down so we will subtract and therefore we can eliminate A
so the answer is B.
lets check our answer by using the formula
Y = lxl + k
moves 2 units down so our k = (-2)
Y = lxl + (-2) [substitute k]
Y = lxl - 2

The range of this function is y is equal to all real numbers such that y 
0.
In order to find the range of y, we must look for the minimum or maximum value. In a quadratic, this number exists at the vertex. To find the vertex, we use the equation -b/2a, where a is equal to the coefficient of x^2 and b is equal to the coefficient of x. Since there is no x, the coefficient is 0.
x value of vertex = -b/2a
x value of vertex = -0/2(1)
x value of vertex = 0
So then we can look for the minimum y value by plugging in the x value into the equation.
y = x^2
y = x^2
y = 0
Therefore the minimum is 0 and there is no maximum.
