What is the smallest positive integer value of x where the exponential function defined by the table below exceeds x^2+3? What is the corresponding value for y? _
x / -3, -2, -1
y/ 1/81, 1/27, 1/9
_

x=2, y=3

x=4, y=27

x=3, y=9

x=5, y=81

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

you can download it here

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
