Consider the exponential function 
By definition, the domain of a function is the set of input argument values for which the function is real and defined.
Let we take 
then 
then 
then 
If we chose larger values of x, we get larger function values.
For example, If we take 
Thus if we choose smaller and smaller values of x. the f unction values will be smaller and smaller functions.
Thus the domain of the function is the set of all real numbers.
Thus the range is limited to the set of positive real numbers. That is, 
If we choose larger values of x, we will get larger function values, as the function values will be larger powers of 2.
If we choose smaller and smaller x values, the function values will be smaller and smaller fractions.

Answer:
Step-by-step explanation:
1000 Ohms
R = 1000
V = 9
I = V / R
I = 9 / 1000
I = 0.009
500000 Ohms
V = 9
I = V/R
R = 500000
I = 9 / 500000
I = 0.000018
Answer:
critical value = 1.645
The 90% confidence interval = ( -22.62, -17.58)
Step-by-step explanation:
Given that:
the sample size 
= 178
the sample size 
= 226
the sample mean 
= 54.4
the sample mean 
= 74.5
population standard deviation 
= 18.58
population standard deviation 
= 9.52
level of significance ∝ = 1 - 0.90 = 0.10
The critical value for 
is 1.645
For the construction of our confidence interval, we use 90% since that is used to find the critical value.
∴
The margin of error = 
2.52
The lower limit = 
= ( 54.4-74.5) - (2.52)
= -20.1 - 2.52
= -22.62
The upper limit = 
= ( 54.4-74.5) + (2.52)
= -20.1 + 2.52
= -17.58
The 90% confidence interval = ( -22.62, -17.58)
