Since both numbers are in the radical just multiply and get sq rt
25 times 4 =100
√100=10 answer
When the lines are parallel then there is no solution to the system of equations.
This happens because the intersection is the solution. And when there is no intersection then there is no solution.
309 times 692 ***********************
The answer is 1.75
because the cost on the y axis goes by fourths
The domain is a discrete set. So we will have a discrete range.
The range is a set containing:
f(-2)=-11
f(-1)=-9
f(0) = -7
f(1) = -5
f(2) = -3
Range = {-11,-9,-7,-5,-3}
