Answer:
f(x/4)
Step-by-step explanation:
The red and orange lines are when f(x) is stretched vertically.
The blue line is when f(x) is stretched horizontally.
Comparing the blue line to f(x), we see that it is 4 times wider. Therefore, the blue line is f(x/4).
Option c is right that is x>-2 because point is open.
Answer:
Solution given:
p=6in
b=8in
By using Pythagoras law
diameter=
=10in
r=5in
Now
Area of shaded region=area of semi circle- area of triangle
=½(πr²)-½p*b
=½(π×5²)-½(6*8)
=15.269
=15.3in² is a required answer.
Answer:
option-c
Step-by-step explanation:
we are given

we will verify each options
option-A:
we can see that exponent is over 3
and it is positive and greater than 1
so, this function is increasing
so, this is FALSE
option-C:
At x=1:


At x=2:





So, it is getting tripled
so, this is TRUE
option-b:
we can plug x=0


so, this is FALSE
option-d:
we can plug x=1


so, this is FALSE
