Answer:
Median: 85
Mode: 85
Range: 20
Mean: 86
Step-by-step explanation:
2/3x -8/3 >= y is the answer
The same input is being mapped into two outputs, so this is not a function.
<h3>
Does the table represent a function?</h3>
A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.
Here we have the table:
x y
4 2
3 3
4 5
5 6
7 7
As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.
Then this table does not represent a function.

We want to solve the Initial Value Problem y' = y + 4xy, with y(0) = 1.
To use Euler's method, define
y(i+1) = y(i) + hy'(i), for i=0,1,2, ...,
where
h = 0.1, the step size.,
x(i) = i*h
1st step.
y(0) = 1 (given) and x(0) = 0.
y(1) ≡ y(0.1) = y(0) + h*[4*x(0)*y(0)] = 1
2nd step.
x(1) = 0.1
y(2) ≡ y(0.2) = y(1) + h*[4*x(1)*y(1)] = 1 + 0.1*(4*0.1*1) = 1.04
3rd step.
x(2) = 0.2
y(3) ≡ y(0.3) = y(2) + h*[4*x(2)*y(2)] = 1.04 + 0.1*(4*0.2*1.04) = 1.1232
4th step.
x(3) = 0.3
y(4) ≡ y(0.4) = y(3) + h*[4*x(3)*y(3)] = 1.1232 + 0.1*(4*0.3*1.1232) = 1.258
5th step.
x(4) = 0.4
y(5) ≡ y(0.5) = y(4) + h*[4*x(4)*y(4)] = 1.258 + 0.1*(4*0.4*1.258) = 1.4593
Answer: y(0.5) = 1.4593
