Answer: Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values, 
and 
, that have the same output value y
Note that the function 
is not a one-to-one function
When x=2 
When x=8 
Note that the function 
is not a one-to-one function
When x=1 
When x=-1 
Note that the function 
is not a one-to-one function
When x=1 
When x=-1 
Then the answer is the option B.
You can verify that The function 
is a one-to-one function and therefore its inverse is a function
Answer:
8 feet
12 inches equals 1 foot, so 8 inches is a lot smaller than 8 feet.
Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
8^2+x^2=10^2
64+x^2=100
x^2=100-64
x=
x=6 km
First we put the equation in y = mx + b form where m is ur slope and b is ur y int.
2x - 5y = 10
-5y = -2x + 10
y = 2/5x - 2.......so ur slope is 2/5 and ur y int is (0,-2) <==
to find ur x int, sub in 0 for y and solve for x
2x - 5y = 10
2x - 5(0) = 10
2x = 10
x = 10/2
x = 5......and ur x int is (5,0) <==
another way to find the y int is to sub in 0 for x and solve for y...but u might as well solve it by putting it in y = mx + b form because that way u have ur slope as well.
Answer:
6
Step-by-step explanation:
Formula - √a * b
= √4 * 9
= √36
= 6
