if x= 2+4y-5 then x-2 +5 = 4y so y = (x-2+5) /4 = ( x+3) /4

conclusion y = (x+3)/4

Find each key feature of the function shown in the graph. Write the range and domain in interval notation, and assume all values

gayaneshka [121]

The domain of the graph is $-8$ while the range of the graph is $-4\leq x$ .

The domain of the graph is input values of "x" for which the function exists while the range is the output values "y" for which the function exists.

For the graph, the domain will be the values of the graph along the x-axis.

Domain = $-8$ (Note that -8 is not included)

For the range, the interval is given as: $-4\leq x$ . Note that the value of 4 is not included since it is opened.

Find the inverse of f(x)=(x−5)/(−4x−2)

uysha [10]

Answer:

${f}^{ - 1} (x)= \frac{ 5 - 2x }{ 4x + 1}$

Step-by-step explanation:

The given rational function is

$f(x) = \frac{x - 5}{ - 4x - 2}$

Let

$y = \frac{x - 5}{ - 4x - 2}$

Interchange x and y

$x= \frac{y- 5}{ - 4y - 2}$

Cross multiply

$x( - 4y - 2)= y- 5$

Expand

$- 4xy - 2x= y- 5 \\ - 4xy - y= 2x - 5 \\y( - 4x - 1)= 2x - 5$

Solve for y;

$y= \frac{ 2x - 5}{ - 4x - 1}$

$y= \frac{ 5 - 2x }{ 4x + 1}$

Therefore

${f}^{ - 1} (x)= \frac{ 5 - 2x }{ 4x + 1}$

Agata [3.3K]

Answer:

32 Roller Coasters

Step-by-step explanation:

There are a total of 112 rides in Cedar Point.

$\frac{2}{7}$ of these rides are roller coasters.

In Algebraic Word Problems, the term "OF" means Multiplication.

Number of Roller Coasters = $\frac{2}{7}$ of 112

= $\frac{2}{7}$ X 112

=2 x 16

=32

There are 32 Roller Coasters in Cedar's point's collection of rides.
