Answer:

Domain: {x | x = -2, 2, 4}

Range: {y | y = -3, 0, 4}

Step-by-step explanation:

Domain of a function includes all possible values of x that are plotted on the x-axis on a grid.

The range includes all possible y-values.

The graph of the function given above has specific points that are marked clearly. Each specific values if x and y are clearly known.

Therefore, the domain of the function are -2, 2, and 4.

This can be written properly as {x | x = -2, 2, 4}

The domain value include -3, 0, and 4.

This can be written as {y | y = -3, 0, 4}

Can someone help me find the value of X and Y ;) I would appreciate it
Svetllana [295]

Step-by-step explanation:

10/2=(x+9)/4= 5y/3

5 =(x+9)/4 = 5y/3

x+9 = 5×4

x+9 = 20

x = 11

5y/3= 5

5y = 15

y = 3

therefore, x = 11 and y = 3

THIS IS 61 POINTS. Find the first three terms of the sequence described by the following recursive formula: an = 3an – 1 + 2 whe
mestny [16]

Answer:

see explanation

Step-by-step explanation:

Given the recursive formula

a_{n} = 3a_{n-1} + 2 and a₄ = 20

Then working in reverse

3a₃ + 2 = 20 ( subtract 2 from both sides )

3a₃ = 18 ( divide both sides by 3 )

a₃ = 6

3a₂ + 2 = 6 ( subtract 2 from both sides )

3a₂ = 4 ( divide both sides by 3 )

a₂ = \frac{4}{3}

3a₁ + 2 = \frac{4}{3} ( subtract 2 from both sides )

3a₁ = - \frac{2}{3} ( divide both sides by 3 )

a₁ = - \frac{2}{9}

Hence

a₁ = - \frac{2}{9}

a₂ = \frac{4}{3}

a₃ = 6

F=f (1-v/s) change the subject of the formula into v
Artyom0805 [142]
Changing the subject of the formula into v means expressing v in terms of the other given variables. So given the original equation, as shown below, we can rearrange it so that we have v isolated on one side.

F = f(1 - \frac{v}{s})
\frac{F}{f} = 1 - \frac{v}{s}
\frac{v}{s} = 1 - \frac{F}{f}

To isolate v, we can just multiply s to both sides and come up with the final equation below.

v = s(1 - \frac{F}{f})

Thus, we have v = s(1 - F/f) with v as the subject of the formula.

Answer: v = s(1 - F/f)
