f(x)=5x^2-2x
f(0)=5*0^2-2*0
f(0)=0-0=0 ans.
f(-1)=5(-1)^2-2(-1)
f(-1)=5*1+2
f(-1)=5+2=7 ans.
f(2)=5*2^2-2*2
f(2)=5*4-4=20-4=16 ans.

Assuming your function is f%28x%29=5x%5E2-2x%29?
f(0)=0 (zero to any power apart from zero is always zero)
f(-1)= 5*(-1^2)+2 = 7
Have a go at the last one yourself! :-)
