Step-by-step explanation:
<u>Exponential Growth Function
</u>
The exponential function is commonly used to model natural growing or decaying processes where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the growth positive rate, expressed in decimal
Nicki paid Co=$245,000 for a house and it's known that home prices increase by r=3.5%=0.035 each year.
a)
Substituting the given values, the equation is:
b) The value of Nicki's house in t=4 years is:
Nicki's house is worth $281,143 in 4 years

<u><em>The complete question is</em></u>
Jaden and Joel both worked at the coffee shop today. Jaden's total cups of coffee made is represented by f(x), and Joel's total cups of coffee made is represented by g(x). Use the functions below to write a function that represents the total cups of coffee they made today.
f(x) = 4x − 1
g(x) = 2x + 3
Options
6x + 2
2x + 1
2x − 4
4x + 4
we know that
To find out the total cups of coffee they made today, sum Jaden's total cups of coffee plus Joe's total cups of coffee
so
f(x)+g(x)
substitute the values

We're looking for C(h), where h is the hundreds of shirts. The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500. Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect. I'll leave it to you to evaluate C(5).
Answer:
D. A positive association between hours studied and test score.
Step-by-step explanation:
The scatter plot appears to have an upward trend.
f(x) cannot be 0 or less than zero, but can approach+ infinity
Answer is (0, ∞)
