Answer:
B (second table in list)
Step-by-step explanation:
The function is a quadratic with vertex and y-intercept at (0,-2). The parabola opens up meaning only y - values above -2 are a part of the function. Since range is the set of all y values, then the range is
.
The domain is not restricted and it is all real numbers.
The inverse of the function is where x and y are switched. So the range becomes the domain and vice verse.
This means the domain of the inverse is
and the range of the inverse is all real numbers.
Answer:
(xy - 4)(xy + 4).
Step-by-step explanation:
The is the difference of 2 squares.
a^2 - b^2 = (a - b)(a + b: so we have:
x^2y^2 - 16 = (xy - 4)(xy + 4)
$4.00 + $2.25* number of miles
$4.00 + $2.25* 8.7= $23.58
Step-by-step explanation:
40=6x+12
we know the total of everything is 40, so out that on one side.
1. Let the number be X
Therefore, six times the sum=6x
and twelve
so, 6x+12
put that together,
6x+12=40
