The function equation represented by the graph is given by the following variable f ( x ) = 5 ( 2/5 )ˣ

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the equation of graph of the function be represented as A

Now , the value of A is

The function is an exponential equation with intercepts at

Let the first point on the graph be A ( 0 , 5 )

Let the second point on the graph be B ( 1 , 2 )

Now , the line is an exponential decay equation of the form

A = 5 ( 2/5 )ˣ

Therefore , the function is f ( x ) = 5 ( 2/5 )ˣ

Hence , the equation of graph is A = 5 ( 2/5 )ˣ and it is plotted

Answer:

I'm here! This Problem is easy :) The answer is 4

Step-by-step explanation:

2x+10=5x−2

Subtract 5x from both sides

2x+10−5x=−2

Combine 2x and −5x to get −3x.

−3x+10=−2

Subtract 10 from both sides.

−3x=−12

Divide both sides by −3.

Divide −12 by −3 to get 4.

Answer:

  A.  r = 4

Step-by-step explanation:

For common ratio r, the second term is ...

  a2 = 3r

The next terms are ...

  a3 = (a2)r = (3r)r = 3r²

  a4 = (a3)r = (3r²)r = 3r³ = 192

Then the value of r is ...

  r³ = 192/3 = 64

  r = ∛64 = 4

The common ratio is r = 4.

Answer:

C

Step-by-step explanation:

Given the 2 equations

3x + 2y = 4 → (1)

- 2x + 2y = 24 → (2)

Multiplying (2) by - 1 and adding to (1) will eliminate the y- term

2x - 2y = - 24 → (3)

Add (1) and (3) term by term to eliminate y

5x + 0 = - 20

5x = - 20 ( divide both sides by 5 )

x = - 4

Substitute x = - 4 into either of the 2 equations and solve for y

Substituting into (1)

3(- 4) + 2y = 4

- 12 + 2y = 4 ( add 12 to both sides )

2y = 16 ( divide both sides by 2 )

y = 8

solution is (- 4, 8 ) → C

Answer:

30 = 5n

n = 6

Step-by-step explanation:

A box of strawberry cost = $5

A person has = $30

Number of boxes a person can buy = n

Equation to calculate the most number of boxes a person can buy with $30

Amount with the person = cost of a strawberry × number of strawberry

30 = 5 * n

30 = 5n

n = 30/5

n = 6

Answer:

(5,45)

Step-by-step explanation:

Hi,

y = 2x + 35

y = 9x

To solve, we can substitute 9x for y.

9x = 2x + 35

Subtract 2x...

7x = 35

Divide by 7...

x = 5

Now plug in 5 for x...

y = 9x

y = 9(5)

y = 45

Your answer is (5,45)

I hope this helps :)

Answer:

x=5, y=45. (5, 45).

Step-by-step explanation:

y=2x+35

y=9x

-------------

2x+35=9x

35=9x-2x

35=7x

x=35/7

x=5

y=9(5)=45

Step-by-step explanation:

I took the test

The equation is f(x) = x² – 8x + 5. Then the y-intercept is at (0, 5) and the function crosses the x-axis twice. Then the correct options are A, D, and E.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The quadratic equation is given below.

f(x) = x² – 8x + 5

Convert the equation into vertex form, then the equation will be

f(x) = x² – 8x + 5

f(x) = x² – 8x + 16 – 16 + 5

f(x) = (x – 4)² – 16 + 5

f(x) = (x – 4)² – 11

The graph of the function is given below.

From the graph, the y-intercept is at (0, 5) and the function crosses the x-axis twice.

Then the correct options are A, D, and E.

Answer:

The average number of cavities is 3.2

Step-by-step explanation:

To find the answer we will put them in order from least to greatest.  

0, 1, 4, 5, 6.  Now add all the numbers up and we get 16.  Because we are trying to find the average number, we will count up how many numbers there are.  Since their are 5 numbers total, we divide 16 by 5 and we get 3.2.  Therefore, 3.2 is our answer.
