Answer:
f(x)=8*(3.5)^x
Step-by-step explanation:
2=98
3= 98r
4= 98r^2
5= 98r^3
6= 98r^4
98r^4/98, 98 crosses out and its just r^4. r^4= 14706.125/98
r=3.5
So you plug that in and you get f(x)=8*(3.5)^x
I hope this helped. XD
The value of b is 4
Step-by-step explanation:
The form of an exponential function is
, where
- a is the initial value (value f(x) at x = 0
- b is the growth/decay factor
- T find the values of a and b substitute x and f(x) by the coordinates of any points belong to the function
∵
∵ The function includes the points (2 , 16) , (3 , 64) , (4 , 256)
- To find b substitute x and f(x) by the coordinates if any point above
∵ x = 2 and f(x) = 16
∴ 
- Take √ for both sides
∴ ± 4 = b
Substitute x by 3 and f(x) 64 to check your answer
∵ 
- Take ∛ for both sides
∴ 4 = b
∴ The value of b is 4 only
The value of b is 4

Answer:
Step-by-step explanation:
4-x<9
-x < 5
x < -5
Answer:
Step-by-step explanation:
2) When x = 6
x - 2y = 8
6 - 2y = 8
-2y = 8 - 6
-2y = 2
y = 2/-2
y = -1
Yes, (6, -1) lies on the line.
3) No, (-2 , -3) is not on the line
4) (-2 , -3) is not a solution to this equation because it does not lie on the line.
Answer:
Quadrant 3
Step-by-step explanation:
Here we have to graph the function y = x/(x^2 + 2x + 1)
The denominator can be factored.
x^2 + 2x + 1 = (x + 1)(x + 1)
y = x/(x + 1)(x + 1)
Now we have to graph this function and see in which quadrant the function's both branches passes through.
Herewith I have attached the graph.
Here we can see both branches pass through Quadrant 3.
I hope this will helpful.
Thank you.
