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)

A graph is shown below.<br><br> Which function represents the graph?
Ede4ka [16]

Given that the graph of a parabola.

We need to determine the function that represents the graph.

<u>Function of the graph:</u>

From the graph, it is obvious, that the x - intercepts of the graph are x = -3,x=-5

Thus, the equation can be written as

y=(x-(-3))(x-(-5))

Simplifying the terms, we have;

y=(x+3)(x+5)

Multiplying, we get;

y=x^2+5x+3x+15

Adding the like terms, we have;

y=x^2+8x+15

Writing it as function, we have;

f(x)=x^2+8x+15

Hence, the function of the graph is f(x)=x^2+8x+15
