Let
x--------> the larger integer
y-------> the smaller integer
we know that
x²+y²=394-----> equation 1
x=y+2-----> equation 2
substitute equation 2 in equation 1
[y+2]²+y²=394-----> y²+4y+4+y²=394
2y²+4y-390=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
y=13
x=y+2---> x=13+2---> x=15
the answer is
the numbers are 15 and 13

Answer:
3025
Step-by-step explanation:
We observe that increasing x by 1 from 0.5 to 1.5 causes the function value to be multiplied by 55 (from 1 to 55).
So, increasing the x-value by 1 again, from 1.5 to 2.5, will again multiply the function value by 55.
f(2.5) = 55·f(1.5) = 55^2
f(2.5) = 3025
