     Set2 2.2: Problem 4 Previous Problem List Next (1 point) A. Find y in terms of x if x y dx and (0) 38. y(x) B. For what x-interval is the solution defined? (Your answers should be numbers or plus or minus infinity. For plus infinity enter \"PINF\"; for minus infinity enter \"MINF The solution is defined on the interval: x  
  
  Solution
a:dy/dx=x4 y-7
dy/y-7=x4 dx
y7 dy=x4 dx
y8/8=x5/5+c
y(x)=y8/8-x5/5+c
y(0)=8
hence,
b:1/8(88)=1/5(85)+c
c=1/8*88/85*5/1
=1/8*83*5/1
=5*82
c=320
x should be o to 1
