Step-by-step explanation:
A. x= 2 y=4
Hoped this is correct.
Step-by-step explanation:
f(x) = x² + 1, where x >= 0.
Let y be f(x).
=> y = x² + 1
=> x² = y - 1
=> x = √(y - 1) because x is non-negative.
Hence f^-1(x) = √(x - 1), where x >= 1.
Answer:
x < -3
Step-by-step explanation:
The domain in which the function is increasing or getting bigger is from x is negative infinity to is -3
x < -3
Answer:
40 Stamps
Step-by-step explanation:
According to the scenario, given data are as follows,
Total stamp collected = 343
Stamps from Germany = 296
To estimate the stamps from other contact, we first round off the given number of stamps.
So, Total stamp collected = 340 ( Rounded off)
Stamps from Germany = 300 ( Rounded off)
So, Stamps from other contact = 340 - 300 = 40 stamps
