Graphing Exponential Function in Exercise ,sketch the graph of the function.See example 3 and 4.

Vlad [161]

Answer:

The attached image shows the graph for the given function.

Step-by-step explanation:

We are given the following function in the question:

$y(x) = 2^{x-1}$

We have to graph the given function.

Properties of the given function are:

It is an exponential function of the form $y(x) = a^{x + b}$
Here, a = 2, b = -1
The y-intercept of the given function is (0,0.5)
There is no x-intercept.
The domain of the given function is all real numbers.
The range of given function is $(0,\infty)$

The attached image shows the graph for the given function.

(9,5) and (4,-7) find the distance between two points

Pani-rosa [81]

Answer:

13 units

Step-by-step explanation:

Use the distance formula, d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$ , where (x2, y2) and (x1, y1) are two different points on the line.

Plug in the values:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

d = $\sqrt{(9 - 4)^2 + (5 + 7)^2}$

d = $\sqrt{5^2 + 12^2}$

d = $\sqrt{25 + 144}$

d = $\sqrt{169}$

d = 13

F(x)=3 over x+2-x-3 squared what is f(7)

dimaraw [331]

Answer:

$f(7)=\frac{-5}{3}$ or $f(7)=-1.67$

Step-by-step explanation:

We are given the following function of x and we are to find the value of $f ( 7 )$ :

$f ( x ) = \frac { 3 } { x + 2 } - \sqrt { x - 3 }$

Substituting the given value (7) in the above function to get:

$f(x)=\frac{3}{x+2}-\sqrt{x-3}$

$f ( 7 )= \ frac{3}{7+2}-\sqrt{7-3}$

$f(7) = \frac { 3 } { 9 } - \sqrt { 4 }$

$f(7)=\frac{1}{3}-2$

$f(7)=\frac{1}{3}-\frac{6}{3}$

$f(7)=\frac{-5}{3}$ or $f(7)=-1.67$
