What is the least possible degree of the polynomial graphed above?
anastassius [24]

Using it's critical points, it is found that the least possible degree of the polynomial graphed above is 4.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

f^{\prime}(x) = 0

At these critical points, the behavior of the function changes from increasing to decreasing or vice versa.

If a function has n critical points, the least possible degree is of n + 1.

From the changes in behavior of the graph, the function has critical points at:

  • x \approx -0.5.
  • x \approx 2
  • x \approx 3.5

The function has 3 critical points, hence the least possible degree of the polynomial graphed above is 4.

Karolina [17]

Answer:

A) x+y=100 \\ ..\    5x + y = 420

Step-by-step explanation:

From the question we are told that:

Five-dollar bill  x

One-dollar bill  y

Total number of bills N=100

Worth of bills w=420

Generally the equation for Total number of bills  is mathematically given by

Since it is made up of five and one dollar bills

Therefore

  x+y=100

Hence the Equation for Total worth of bills is

 5x+y=420

The System of equations used is

A) x+y=100 \\ ..\    5x + y = 420

A school had $3,000 to spend on technology. They spent $350 on a new projector. The function f(x)=299x+350 gives the total amoun
sergeinik [125]

Answer:

The y-intercept of the function will not change.

Step-by-step explanation:

The given function is:

f(x)=2x-4

It is defined on the domain

.

We need to find the range:  

The range is the set of output values.  

2\leq x\leq 6

Multiply 2 on each side.  

4\leq 2x\leq 12  

Subtract 4 from each side.  

4-4\leq 2x-4\leq 12-4  

0\leq f(x)\leq 8  

0\leq y\leq 8  

The range of the function is .

Therefore, the correct option is A. The y-intercept of the function will not change.
