Answer:
If f and h are inverses, then:
f (h(x) ) = x and also
h( f(x) ) = x
Step-by-step explanation:
Inverse function: The function f(x) goes from domain to range and the inverse function f^{-1} goes from Range to domain
Option C is correct
I would appreciate it if you marked me brainliest :)
Answer:
The correct answer is option c) (5,0) and (5,-2)
Step-by-step explanation:
In the option c the coordinates of two points lie on x= 5
When we substitute the required points in graph we can see clearly that the coordinates of two points lie on x = 5
<em>HAVE</em><em> </em><em>A NICE DAY</em><em>!</em>
<em>THANKS FOR GIVING ME THE OPPORTUNITY</em><em> </em><em>TO ANSWER YOUR QUESTION</em><em>. </em>
Answer:
the first one
Step-by-step explanation:
multiply by 4 subtract 2
8 hrs a day for 5 days a week = (8 * 5) = 40 hrs per week
in 6 weeks.....40 * 6 = 240 hrs <==
Solve for k:
X^2 + (y - k)^2 = 21
Subtract X^2 from both sides:
(y - k)^2 = 21 - X^2
Take the square root of both sides:
y - k = sqrt(21 - X^2) or y - k = -sqrt(21 - X^2)
Subtract y from both sides:
-k = sqrt(21 - X^2) - y or y - k = -sqrt(21 - X^2)
Multiply both sides by -1:
k = y - sqrt(21 - X^2) or y - k = -sqrt(21 - X^2)
Subtract y from both sides:
k = y - sqrt(21 - X^2) or -k = -sqrt(21 - X^2) - y
Multiply both sides by -1:
Answer: k = y - sqrt(21 - X^2) or k = sqrt(21 - X^2) + y
