The domain and range of a function are the possible <em>x and y values </em>of the function.
<em>The domain and the range of the function is: (a) </em><em> and </em><em />
The functions are given as:
(g o f)(x) is calculated as:
So, we have:
Take LCM
Represent the denominator as follows, to calculate the domain
Add 4 to both sides
Take square roots of bot sides
Hence, the domain of the function is:
On the graph of (see attachment), the function does not have a value from <em>y = 1 to 2.</em>
Hence, the range is:

Answer:
416
Step-by-step explanation:
Standard deviation is 2.6
Margin error for the problem is 0.25
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
.25 = 1.96 * 2.6/ √n
0.25 = 5.096/√n
√n = 5.096 /0.25
√n = 20.38
n = 20.38^2
n = 415.5 = 416
<span>y=4x+8 is a linear function with slope 4 and y-intercept 8.
If x=0, y=8; the y-intercept is (0,8).
If x=1, y=4(1)+8 = 12
If x=5, y=28
and so on</span>
