You can put this solution on YOUR website!
x = 5

f%28x%29+=+1+%2B+19x+%2A+x Start with the given equation.


f%285%29+=+1+%2B+19%285%29+%2A+5 Plug in x=5


f%285%29+=+1+%2B+475 Multiply


f%285%29+=+476 Add

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

x = 1

f%28x%29+=+1+%2B+19x+%2A+x Start with the given equation.


f%281%29+=+1+%2B+19%281%29+%2A+1 Plug in x=1


f%281%29+=+1+%2B+19 Multiply


f%281%29+=+20 Add
