Use euler's method with step size 0.5 to compute the approximate y-values y1, y2, y3 and y4 of the solution of the initial-value problem y' = y − 3x, y(4) = 2.

Step-by-step explanation:

Given is a differential equation

Here we have

To find y1, y2, y3, y4

Step size = 0.5

y_1 = y_0 +0.5f(x_0,y_0)

Here f(x,y) = y-3x

Applying this successively we get

y1 = 2+0.5(2-12) = -3

y2 = -3+0.5(-3-13.5) = -11.25

y3 =-11.25+0.5(-11.25-15) =-24.375

y4=-24.375+0.5(-24.375-16.5)=-44.8125

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
