Answer:
See below in bold.
Step-by-step explanation:
The domain is the list of x values and the range is the list of y values.
Reading from the graph: The domain is {-3.5, -2, 0, 3.5}.
The range is {3, 1.5, -0.5, }.
So it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation
the factored out form is
factor out the 3x^2 and get
(3x^2)(3x^2-2x+1)
and 3x^2-2x+1 is the fourth choice
Lets say the number is ab. Its value is 10a + b
When it is reversed it is 10b + a = 12a+1.2b (from the condition its value should increase 0.2 times).
11 a = 8.8b
a/b = 8.8/11 = 0.8/1 = 8/10 = 4/5 ( we do this because a and b should be natural numbers less than 10).
answer is 45.
The answer is 0.08 or you could say 8 * 10^-2.
Reasoning..
6.4 * 10^3 = 6400
8 * 10^4 = 80000
Divide those two numbers like shown in the problem and boom!
