Decide whether the table represents a linear or exponential function circle with a linear exponential then write the function fo

Sergio [31]

This function starts at $(0,3)$ , so we have $f(0)=3$ .

Then, every time $x$ increments by 1, $y$ doubles. This is typical of exponential functions. In linear functions, every time $x$ increments by 1, $y$ increments by a fixed amount (the slope of the function).

So, this is an exponential function, and the equation is

$f(x)=3\cdot 2^x$

Find the distance between K(9, 2) and L(–3, 9) to the nearest tenth.

Bas_tet [7]

d = √[(-3-9)²+(9-2)²]

= √[144+49]

= √194

= 13.9

2(2x + 3) = -6(x + 9)

sergeinik [125]

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.

The inverse, f'(x), of f(x) =

astraxan [27]

Step-by-step explanation:

Given

$f(x) = \frac{x + 5}{x}$

$f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2}$

Now

${f}^{ - 1} (x) = \frac{5}{x - 1}$

${f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5$

Hope it will help :)❤
