Examples :
(-2)^3 = (-2)(-2)(-2) = - 8

(-3)^4 = (-3)(-3)(-3)(-3) = 81

(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1

** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative

** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25

Any number raised to a negative exponent could be written as follows:

a⁻ⁿ = 1/aⁿ

a⁻² = 1/a²

a⁻²³ = 1/a²³

a⁻ˣ = 1/aˣ

What is the inverse of the function f(x) = 2x + 1?

hodyreva [135]

Answer:

The inverse f-1(x) = ( x - 2) / 2.

Step-by-step explanation:

Let 2x + 1 = y

Now find x in terms of y:

2x = y - 1

x = (y - 1) / 2

Replace the x by the inverse f-1(x) and the y by x, so we have:

f-1(x) = ( x - 2) / 2.

30 POINTS!!!! I NEED AN ANSWER!!PLEASE HELP!

Harman [31]

Answer:

Its the last one: a translation 2 units right and 4 units down.

Step-by-step explanation:

To get from point E (1,3) to E' (3-1) you add 2 units to the x coordinate since the x-axis goes from left to right and moving to the right means its positive and then you subtract 4 from the y coordinate since the y axis is going up and down and when you move -4 points you move down 4 points. You do this to every other point get the new figure.

Which equation represents a linear function?

Mila [183]

The equation y - 2 = -5(x - 2) represents a linear function ⇒ 1st answer

Step-by-step explanation:

A linear function is any function that graphs to a straight line

(not a vertical line)

The forms of the linear equation are

y = m x + b, where m is the slope of the line which represents the function and b is the y-intercept ⇒ slope-intercept form
$y-y_{1}=m(x-x_{1})$ , where m is the slope and $(x_{1},y_{1})$ is a point lies on the line which represent the function ⇒ slope-point form
Ax + By = C, where A, B, and C are constant ⇒ standard form
