*PLEASE EXPLAIN*
The initial value of the function is 2.5.
The function increases by a factor of 2.5 for each unit increase in x.
The domain of the function is all real numbers.
The range of the function is all real numbers greater than 3.
The statements which are true of the function; f(x) = 3(2.5)^x and there explanations are below;

This is an exponential function since the x is in the exponent's place instead of in the place of a "regular" variable. The first statement is true.
The initial value of this particular function is 3 (the other number is the multiplier), so choice 2 is NOT true.
The function increases by its multiplier, which is 2.5, so statement 3 is true.
The equation allows us to enter any x value we want to determine the y, so the domain is in fact all real numbers. So, this statement is also true.
If you were to graph this on a calculator, you would see that the range, the "allowed" y values for our function, do not touch or ever drop below the x-axis. That means that the range is all numbers greater than 0. So that statement is false. No matter what value we pick for x, we will NEVER get back a negative y value or that y = 0. For example, if x = 0, y = 3; if x = -5, y = .03; if x = -10, y = .0003; if x = 5, y = 292.97; if x = -100, . Y will never be equal to 0 or less than 0.
The equation of line passes through points and in standard form is .
Further explanation:
It is given that a line passes through points and .
The slope of a line passes through points and is calculated as follows:
......(1)
Here, the slope of a line is denoted as and points are and .
Substitute for , for , for and for in equation (1) to obtain the slope of a line that passes through points and .
Therefore, the slope is .
The point-slope form of the equation of a line with slope passes through point is represented as follows:
......(2)
Substitute for , for and for in equation (2) to obtain the equation of line.
Therefore the standard equation of line that passes through points and is .
Thus, theequation of line passes through points and in standard form is

Answer:
$106
Step-by-step explanation:
The formula given for Monthly payment of a loan =
P × [ r (1 + r)/(1 + r)^n - 1
Where
r = interest rate
n = number of monthly payments
P = Present value of the loan
From the question,
r = interest rate, we were told to ignore hence, r = 0
P = $3,175
n = 30
Hence,
Amount to be paid monthly = P/n
= $3175/30
= $105.83
Approximately to the nearest dollars
= $106
