hello buddy!
f(1)= 5(1)2-4(1)+5
=26
f(-1)=5(-1)2-4(-1)+5
=34
f(0)=5(0)2-4(0)+5
=5
adding all according to the question!!
26+34+5
=>65.
answer!
hope this would have helped you!

Answer:
f(x)=5x^2-4x+5
when x= 1
f(1)=5×(1)^2-4×1+5
=5-4+5=6
when x= -1
f(-1)=5×(-1)^2-4×(-1)+5
=5+4+5=14
when x=0
f(0)=5× (0)^2-4(0)+5
=0-0+5
=5
ATQ,
f(1)+f(-1)+f(0)=6+14+5=25.
hope it helps.
