Answer:
(-∞, ∞).
Step-by-step explanation:
f(x) = is a polynomial function, so the domain is all real numbers (you can enter any value of x and i till return a valid y value). In interval notation is (-∞, ∞).
V(t)=875-50t

The rate of interest is 13%.
Step-by-step explanation:
Given,
Principal (P) = $560
Interest (I) = $145.60
Time (T) = 2 years
To find the rate of interest
Formula
If P principal was invested for T years at r% simple interest, the interest will be I =
So,
Putting the values of P, I, T we get,
145.60 =
or, r =
or, r = 13%
Hence,
The rate of interest is 13%.
The function g(x) has a greater slope and the function f(x) has a greater y-intercept
<h3>How to compare the slopes?</h3>
The function is given as:
Function f(x)
x f(x)
-1 -6
0 -3
1 0
g(x) = 4x - 5
The slope of f(x) is calculated using:
This gives
Evaluate
m = 3
By the general format of a linear equation, the slope of the function g(x) is:
m = 4
4 is greater than 3
Hence, the function g(x) has a greater slope
<h3>How to compare the y-intercepts?</h3>This is when x = 0
For the function f(x), we have:
f(0) = -3
For the function g(x), we have:
g(0) = 5-
-3 is greater than -5
Hence, the function f(x) has a greater y-intercept
