Consider the graph of the polynomial function below.
VARVARA [1.3K]

Answer:

  1. The degree of the polynomial is even.
  2. The leading coefficient is positive.
  3. The polynomial has four zeros.

Step-by-step explanation:

As shown at the graph

The polynomial function intersects with x-axis at 4 points and opens up.

So, we can deduce that:

1) The degree of the polynomial is the fourth degree because it have  4 points of intersection with the x-axis

So, The degree of the polynomial is even

2) As the curve opens up ⇒ The leading coefficient is positive

Leading coefficients are the numbers written in front of the variable with the largest exponent.

3) The polynomial has four zeros because it have 4 points of intersection with the x-axis

The zeros of the polynomial are the values of x at which y = 0

How are the graphs of the functions f(x) = /16x and g(x) = 3/64x related
seropon [69]

Answer:

the functions f(x) and g(x) are equivalent

Step-by-step explanation:

Your full question is attached below

The equations of your problem are

f(x) = √(16^x)

f(x) = √(4^(2x))

f(x) = √(4^(2x)) = √(4^x.4^x)

f(x) = 4^(x)

and

g(x) = ∛64^x

g(x) = ∛4^(3x)

g(x) = ∛4^(3x)  =  ∛4^(x) .4^(x) .4^(x)

g(x) = 4^(x)

Thus, the functions f(x) and g(x) are equivalent

iris [78.8K]

Answer:

The total income of designer from this work is $1649.6.

Step-by-step explanation:

The fees charged by the designer = $1600

The commission on total sales = 8%

Total sales amount in the festival =  $620

Now, 8% of $620 = \frac{8}{100}  \times 620 = 49.6

So, the commission on total sales = $49.6

Also, Total Income of the designer = Deign Fee + 8% Commission fee

= $1600 + $49.6

= $1649.6

Hence, the total income of designer from this work is $1649.6.
