For each example below, find the values of the parameters so that the function satisfies the differential equation. If there is more than one correct value, separate them by commas (e. g. 3,2). enclosing them in "curlies" (e. g. {3,2}) is optional. a. y(x) = xr satisfies y' = 9y/x if r =b. y(x) = xr satisfies y' = â11y/x if r =c. y(x) = ex+rx+sx2 satisfies y'' â y' = 4x if r = , and s =d. y(x) = erx+sx satisfies y'' â 4y= x if r = , and s =
