A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2
Range is the lowest to highest Y value so (-3,3)
(-5,-2) - domain
(-3,3) - range
B Intercept are when the line crosses the acis labeled x so
(-2,0) and (2,0)
C F(1) means what is x when y is equal to 1 so we must estimate this
(-1,1) and (1.5,1)
D f(x) = -3 is when y is -3 so we look at the graph to see
-5 and 4 are the values for x
E f(x) < 0 means when y is above the x axis
This is between the x values of -2 and 2 or (-2,2)

Answer:
The loan was for 9 months only
Step-by-step explanation:
In this question, we are concerned with calculating the time taken for a loan om an interest to be paid back
To calculate this, we use the simple interest formula
Mathematically;
I = PRT/100
where P is the principal which is the amount borrowed and that is $500 according to the question
R is the rate which is 8% according to the question
Interest can be calculated by subtracting the principal from the amount paid back = 530-500 = 30$
We now plug these values into the equation
30 = (500 × 8× T)/100
100 × 30 = 4000T
T = 3000/4000
T = 0.75 (same as 0.75 × 12 months = 9 months)
I believe the equation is
![4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}](https://tex.z-dn.net/?f=4%20%5Csqrt%5B4%5D%7B2x%7D%20%2B%206%20%20%5Csqrt%5B4%5D%7B2x%7D%20)
In this case, you would simplify it by adding them together.
=
![10 \sqrt[4]{2x}](https://tex.z-dn.net/?f=10%20%20%5Csqrt%5B4%5D%7B2x%7D%20)
And can even be changed to an exponential equation:
