What must be a factor of the polynomial function fx) graphed on the coordinate plane below?
Reptile [31]

See in the explanation

<h2>Explanation:</h2>

Hello! Recall that you need to write complete questions in order to get good and precise answers. However, I'll try to explain this problem in a general way. The definition of polynomial functions states:

A \ \mathbf{polynomial \ function} \ of \ x \ with \ degree \ n \ is \ given \ by:\\ \\ f(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+\ldots +a_{2}x^{2}+a_{1}x+a_{0} \\ \\ where \ n \ is \ a \ nonnegative \ integer \ and \ a_{n}, a_{n-1}, \ldots a_{2}, a_{1}, a_{0} \\ with \ a_{n}\neq 0

Suppose we have the following polynomial function:

f(x)=x^3+x^2-8x-12

If (x-3) is a factor of this polynomial function, we can write f(x) as:

f(x)=\left(ax^2+bx+c\right)\left(x-3\right)

In whose case:

f(3)=0

Evaluating x=3

f(x)=x^3+x^2-8x-12 \\ \\ f(3)=3^3+3^2-8(3)-12 \\ \\ f(3)=27+9-24-12 \\ \\ f(3)=32-32 \\ \\ f(3)=0

So in conclusion:

(x-3) \ is \ a \ factor \ of \ f(x)=x^3+x^2-8x-12

The graph is shown below and is consistent with our conclusion.

A factory produces 1,250,000 toys each year. The number of toys is expected to increase by about 150% per year. Which model can
dusya [7]

For this case we have a function of the form:

n (t) = n0 * (b) ^ t

Where,

n0: initial amount (in units of millions)

b: growth rate

t: time in years

Substituting values we have:

n (t) = 1.25 * (2.50) ^ t

Answer:

the number of toys being produced, n (in millions), in t years is:

D. n = 1.25 (2.5 ^ t)

2x^2 + 9x +12+3x+2 8x^2 write an equivalent expression.
Alex73 [517]

Answer:

10x^2 + 12x + 14

Step-by-step explanation:

Combine like terms: 2x^2 + 8x^2 = 10x^2 , 9x + 3x = 12x , 12 + 2 = 14

In total: 10x^2 + 12x + 14

What will be the maximum height <br><br> h (t)=-16t^2+128t+320
Korvikt [17]
To determine the maximum height, h, from the given above. Differentiate the function and equate to zero. Then, determine the value of t. The value, when substituted to the original function, will give the maximum height. For this given, 
                                           dh(t)/dt = -32t + 128 = 0, t = 4

Substituting t = 4 to the original function gives 320. Thus, the maximum height is 320 units.
