You can put this solution on YOUR website!
f%28x%29=4x%5E2-5x
Wherever there is an x, replace it with the actual value,
f%280%29=4%280%29%5E2-5%280%29
f%280%29=4%280%29-0
f%280%29=0

f%28-1%29=4%28-1%29%5E2-5%28-1%29
f%28-1%29=4%281%29%2B5
f%28-1%29=9

f%282%29=4%282%29%5E2-5%282%29
f%282%29=4%284%29-10
f%282%29=16-10
f%282%29=6
Here's a graph of the function, and the 3 points.
