f%28x%29+=+-5x+%2B+1


f%283%29+=+-5%283%29+%2B+1 Replace every x with 3 (since x = 3)


f%283%29+=+-15+%2B+1


f%283%29+=+-14


-------------------------------------------------------


f%28x%29+=+-5x+%2B+1


f%286%29+=+-5%286%29+%2B+1 Replace every x with 6 (since x = 6)


f%286%29+=+-30+%2B+1


f%286%29+=+-29


-------------------------------------------------------


f%28x%29+=+-5x+%2B+1


f%28-3%29+=+-5%28-3%29+%2B+1 Replace every x with -3 (since x = -3)


f%28-3%29+=+15+%2B+1


f%28-3%29+=+16


=======================================================


Summary:


f(3) = -14


f(6) = -29


f(-3) = 16
