It is actually the top one on the second picture because if you were to rotate it 180 degrees, it would end up on the same points
Answer:
f(x) is a one to one function.That maps out one function to another ,and it therefore passes both the vertical and horizontal I ine test
Answer:
Step-by-step explanation:
We need to find the value of x so that the value of given function becomes 21 .
We have ,
Now , for finding x ,
Answer:
12 and 13
Step-by-step explanation:
(a)
To evaluate f(g(2)), evaluate g(2) then use the value obtained to evaluate f(x)
g(2) = 2(2) - 1 = 4 - 1 = 3, then
f(3) = 3² + 3 = 9 + 3 = 12
--------------------------------------------
(b)
To evaluate g(f(2)), evaluate f(2) the use the value obtained to evaluate g(x)
f(2) = 2² + 3 = 4 + 3 = 7, then
g(7) = 2(7) - 1 = 14 - 1 = 13
-5- is the correct answer
