us pascal triangle
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
each number is the sum of 2 above it and the 1's are on the outside because only 1 number is above them and its 1
so since its ^4 we use row 4 (actually the 5th because the top row is row zero)
these at the coefficients
so here is
1a^4b^0-4a^3b^1+6a^2b^2-4a^1b^3+1a^0b^4
or easier to see it vertically
notices how exponential start a 4 and 0 until 4 goes down to 0 and 0 goes up to 4
(3x - 1)
a = 3x
b = -1
1a^4b^0 = 1(3x)^4(-1)^0
-4a^3b^1 = -4(3x)^3(-1)^1
+6a^2b^2 ....
-4a^1b^3 .....
+1a^0b^4....
then write it horizontally
I think you see now, when you expand this you will have your answer
Answer is a
because i remember getting ask this question
The domain of (bºa)(x) is all real number
Step-by-step explanation:
Given
We will find the composition first
so,
As there is no denominator involved in the functions, there will be no input that will approach the function to infinity so the function will be defined on all real numbers
So,
The domain of (bºa)(x) is all real number

Answer:
y=2x+1
Step-by-step explanation:
the y intercept is at 1 and the slope u can just tell from the graph cuz rise over run so 2 over 1 which is 2
Answer:
see the explanation
Step-by-step explanation:
Let
t ---> the number of years since 2017
y ---> the population of the Tallahassee metropolitan area
we have
we have
---> initial value or y-intercept (population for t=0)
substitute the given values
For the year 2025
we have
substitute in the formula
using a graphing tool
The graph in the attached figure
