Question

dada a função f(x)=2x^2-9x+11 calcule f(0)+f(-1)-f(1) me ajudem por favor

Answer 1

f(x)=2x^2-9x+11

f(0)=2.0²-9.0+11
f(0)=2.0-9.0+11
f(0)=0-0+11
f(0)=11

f(-1)=2.-1²-9.-1+11
f(-1)=2.1+9+11
f(-1)=2+9+11
f(-1)=22

f(1)=2.1²-9.1+11
f(1)=2.1-9+11
f(1)=2-9+11
f(1)=4

f(0)=11   f(-1)=22 f(1)=4

f(0) + f(-1) - f(1)
11+22-4
33-4
