The domain are all real numbers
The range are all real numbers
Thus the statements that hold are:
</span><span>2.As x approaches negative infinity, y approaches negative infinity.
</span><span>3.The domain of the function is all real numbers.
</span><span>5.The graph has a positive y-intercept.</span>
Answer:
(7/4)x - 10
Step-by-step explanation:
y = mx + c
m = gradient
c = y-intercept
so you just substitute in the respective values
Answer:
P(not getting a ticket for 2 days) = 0.49
Step-by-step explanation:
We are told that the probability of getting a ticket on any given day is 0.3.
Thus;
P(getting a ticket a day) = 0.3
This means that;
P(not getting a ticket a day) = 1 - 0.3 = 0.7
Now, 0.7 is probability of not getting a ticket for 1 day. Since each day's outcome is independent of the previous day's outcome, it means that for n days, probability of not getting a ticket for n days will be;
P(not getting a ticket for n days) = 0.7ⁿ
For 2 days, its = 0.7² = 0.49
Thus;
P(not getting a ticket for 2 days) = 0.49
Answer:
Option 4
Step-by-step explanation:
Given function is,

Steps to get the inverse of the given function,
Step 1,
Convert the function into equation,

Step 2,
Interchange the variables 'x' and 'y',

Step 3,
Solve the equation for the value of y,






Step 4,
Convert the equation into inverse function,

For x-intercepts,
Substitute y = 0,





Therefore, x-intercept of the inverse function is
.
Option 4 will be the answer.
